The invention relates to the field of electrical engineering, in particular in the transmission of power through the voltage Converter, working in the oscillatory regime, for example through a single-ended voltage Converter.

Known methods of energy transfer through single-ended voltage Converter, or consisting in the direct transfer of electrical energy from the primary source to the load mode, when you open both the switch and the rectifier preobrazili to the load, or in the preliminary accumulation of energy in the magnetizing inductance of the transformer away from the primary source, which open the switch and shut down the rectifier, and then transfer accumulated in the transformer of energy to a load when you hit the switch and open the rectifier [1,2].

Known voltage converters containing coupled with a power source switch, which is connected through a transformer with a rectifier connected load [1,2].

A disadvantage of the known methods and devices is reduced, the energy transferred through the inverter to the load.

There is a method of transferring energy through the voltage Converter, containing connected with a power source switch, which is connected through a transformer with a rectifier that is connected to the load, namely, that open at the same time, the switch and the rectifier and transfer the energy to the power source to the load, and then they simultaneously close and cease transmission of energy to the load [2].

Known single-ended voltage Converter, selected as a prototype of the proposed device contains combined the CAD [2].

A disadvantage of the known method and device is reduced, the energy transferred from the power source to the load. This is because does not use the transformer from the point of view of energy transfer from source to load.

The aim of the invention is to increase the energy transmitted from the power source to the load by transferring energy directly from the power source to the load and transfer the load of energy stored previously in the inductance of the transformer.

This goal is achieved by the fact that in the method of transferring energy through the voltage Converter, containing connected with a power source switch, which is connected through a transformer with a rectifier that is connected to the load, namely, that open at the same time, the switch and the rectifier and transfer the energy to the power source to the load, inputs and connecting the transformer to the switch corrector off switch closes the switch when the energy stored in the transformer close to the maximum, and added, connecting the transformer to the switch corrector enable com is set objective is achieved by the fact that in single-ended voltage Converter containing connected with a power source switch, which is connected through a transformer with a rectifier that is connected to the load inputs of the corrector off switch connecting the transformer with commutation, and corrector enable switch connecting the transformer to the switch.

The introduction of the offset enable switch and corrector off switch and connection with the transformer and the switch provides, according to the method, the on and off switch for transferring energy to the load directly from the power source and the transmission to the load of energy stored previously in the transformer. A comparison of the proposed technical solutions with prototype has allowed to establish their compliance with the criterion of "novelty".

The study of other known technical solutions in this field of technology features that distinguish the claimed invention from the prototype, have not been identified and because they provide the claimed technical solution according to the criterion of "significant differences".

In Fig. 1 shows a method of transferring energy through the conversion of the example of implementation single-ended voltage Converter.

Implementation of the proposed method is illustrated with the help of the device shown in Fig. 1.

Single-ended voltage Converter contains connected to a power source 1, the switch 2, which is connected through a transformer 3 rectifier 4 which is connected to the load 5.

Corrector enable switch 6 connects the transformer 3 with the switch 2. Concealer off switch 7 connects the transformer 3 with the switch 2.

The voltage Converter operates as follows. When the supply voltage from the power supply 1 to the voltage Converter is switched on switch 2.

In the circuit of the power supply 1 switch 2 - transformer 3 appears increasing current. At the same time increases the voltage on the secondary winding of the transformer 3 and through the rectifier 4, the energy is transferred to the load 5. Upon reaching the secondary winding of the transformer 3 maximum voltage corrector off switch 7 beeps on off switch 2. The latter is switched off and the current in the circuit of the power source is interrupted. The polarity of the voltages on the windings of the transformer 3 is reversed source and the load comes reminicient core of the transformer by the end of the transmission to the load 5 accumulated in the transformer 3 energy when the magnetic state of the core of the transformer 3 has the opposite of the original corrector enable switch 6 sends a signal to switch on the switch 2. The latter is turned on and the process of energy transfer from source 1 to the load 5 is repeated.

Below is a specific example of implementation of the proposed method.

The inventive method implemented on a single-ended voltage Converter circuit shown in Fig. 2.

Single-ended voltage Converter contains connected to a power source 1, the switch 2, which is connected through the transformer 3 with a full-wave rectifier 4 which is connected to the load 5. Corrector enable switch 6 connects the transformer 3 with the switch 2. Concealer off switch 7 connects the transformer 3 with the switch 2.

Switch 2 contains the transistor 8 is connected by a collector resistor 9. The transformer 3 has a primary winding 10 connected to the feedback winding 11 and secondary winding 12 is connected to the rectifier 4.

Corrector enable switch 6 is composed of a resistor 13 connected to the diode 14. Concealer off switch 7 consists of posledov supply 1 is connected to the switch 2 to the junction of the collector of the transistor 8 and a resistor 9. 2 switch emitter of transistor 8 is connected to the junction of the primary winding 10 and a feedback winding 11 of the transformer 3. Another output feedback winding 11, placed in series with the capacitor 18 through the capacitor 18 is connected to the diode 16 corrector off 7 and the diode 14 corrector enable 6. 2 switch and a resistor 9 is connected to the corrector enable 6 to the junction of resistor 13 and diode 14, and also connected to the base of the transistor 8 to the corrector off 7 to the junction of resistor 15 and diode 17, which is connected with the emitter of the transistor 8 switch 2.

Single-ended voltage Converter operates as follows. When the supply voltage from the power supply 1 to the inverter circuit power supply 1 - resistors 9, 13 - emitter junction of transistor 8 to the winding 10 of the transformer 3 occurs in the initial shock. This current is insufficient to open the transistor 8 and the latter is closed. From the initial current in the winding 10 is induced voltage on winding 11. This voltage is differentiated by the capacitor 18 is connected in series with the feedback winding 11 of the transformer 3, and the signal is fed through a checker enable 6 (diode 14, resistor 13) on the emitter mutator 2 on transformer 3 (coil 10). In the winding 10 appears increasing current. Energy from the primary winding 10 is transformed into the secondary winding 12 of the transformer 3 and then through the rectifier 4 is transmitted to the load. Upon reaching the secondary winding 12 maximum voltage simultaneously reaches the maximum value, the voltage on the feedback winding 11. When the voltage on the coil 11 after reaching the maximum value changes the sign of the derivative of the voltage signal from the transformer 9 (with winding 11 through the condenser 18) is supplied to the corrector off 7. The current passes through the diode 16 and the resistor 15, the diode 17, which ensures the locking of the transistor 8 of the switch 2. The current in the circuit of the power source 1 is interrupted, and simultaneously changing the polarity of the voltage on the winding 12 on the opposite source and to the load 5 through the rectifier 4 receives the energy stored in the transformer 3 during the previous time interval. At the same time and alternating magnetization of the core of the transformer 3. By the end of the transmission accumulated in the transformer 3 power to the load current through the corrector off stops and you receive the current in the circuit corrector enable 6 and through the emitter junction of transistor 8 to the Affairs allows to double the energy transmitted from the power source to the load, compared to a method and a device for a similar purpose (prototype).
