(57) Abstract: Usage: the invention relates primarily to the field of agricultural production and may find application in the storage of food and agricultural products, as well as to power the lights and heaters, arc welding apparatus and other facilities on the basis of mnogoaktnyh converters. The inventive when making the circuit with the resonant load the object to be processed is the error term, and the efficiency of the Converter is significantly reduced. However, the automatic adjustment of the generated frequency allows you to work in the optimum range. 1 C.p. f-crystals, 1 Il. The invention can find application in agricultural work during the storage of food and agricultural products, soil, greenhouse agriculture, processing of agricultural tools. In addition, you can use the device in the high frequency heating apparatus, high-frequency converters to power the light sources, in units of electric arc welding and other facilities with high-frequency energy conversion constant voltage on the basis of dvocacy resonant inverter, performed on static induction transistors, resonant load, the shapers of control pulses [1]A disadvantage of the known device consists in a large decrease in the efficiency and reliability of the device when you change the load parameters associated with the change in the degree of saturation induction transistors, and the misalignment of the circuit and oscillator. The major advantage of the device is a hard dependency of his work from the electrical state of the power transistor and the load settings: the formation of an enabling pulse power transistor is provided only with a reliable off paraphase key and resonance in the load at the same time. As a result, the inverter and the transistors of the driver control pulses is protected from crashes when switching from the resulting short circuit in the circuit of the source power supply. High precision tracking resonance provides maximum efficiency of energy transfer to the load. Also provides short circuit protection in the circuit of the gate-source of the power transistors. Simplified management and improved size, weight and power while Britney communication and using locked loop. Increased reliability due to the growing noise of the Converter, because the moment of switching on two-rail power transistor is determined by the moment of actuation of the optocoupler. Up to this point the voltage is locked on power transistor is changed relatively slowly. As a result, reduced the effect of Miller and increases the immunity of the Converter. The combined effect of optical feedback and auto-tuning of resonance allows to bind all switching to the zero power current, which improves the reliability of the Converter. A significant drawback of the known device is the abrupt change in the degree of saturation and the depth of the locking of the power transistors. The introduction of additional feedback at high frequency in an additional embodiment, the Converter allows you to change the unlocking and locking the currents of the power transistors is proportional to an output current, which ensures reliable operation of the Converter with pulsating power voltage. The drawing shows a structural diagram of the Converter of electrical energy. The Converter contains a push-pull resonant inverter 1 in the form of a static induction transistory 7, the emitter 8 optocoupler 9, connected in series with the resistor 10 is connected in parallel to the input of the static induction transistor 2, the emitter 11 photo coupler 12 is connected in series with a resistor 13 and they are connected in parallel to the input of the static induction transistor 3, the outputs of the photo-coupler 9, 12 are connected with the first inputs of the blocks match 14, 15, respectively, the input unit of the automatic frequency control 16 is connected to the output of block matching 7, and its two-rail output is connected with the emitters 17, 18 of the photo-coupler 20, 21, the output of the optocoupler 20 is connected to the second input unit 15 matches the output of the optocoupler 21 is connected with the second input unit 14 matches, the outputs of blocks matches 14, 15 are connected to the inputs of pulse shapers management 6, 5, respectively. In the variant of the Converter according to p. 2 anode cut-off of the diode 23 and the cathode of the clip diode 24 is connected to the output of the block matching 7, the cathode of the clip 23 is connected in series with a resistor 25 and connected to the drain of the FET 26 and the first surface forcing of the capacitor 27, the second plate of the capacitor connected to the source of the static induction transistor 2, the anode of the clip diode 24 is connected in series with resista lining is connected to the source of the static induction transistor 2, the cathode of the clip diode 31 is connected to the drain of the FET 26, the anode of this diode is connected with the positive pole of the voltage source 32, the anode of the clip diode 33 is connected to the drain of the field-effect transistor 29, the cathode of the diode to the negative pole of the voltage source 34. A Converter of electrical energy works in the following way. Let the initial state, both of the power transistor 2, 3 inverter 1 is locked and the gates of these transistors is supplied with a negative voltage. When the power supply voltage unit of the automatic frequency control 16 generates a control pulse which is positive paraphase output is fed through a resistor 19 to the emitter 17 of the optocoupler 20, and then output optocoupler 20 to the input unit 15 matches. On both inputs of the block matches 15 is a logical unit, to the input of the pulse shaper 5 receives an enabling pulse and the power transistor 2 is switched on. High-frequency signal to the load through the power of reconciliation 7 is again sent to the input unit 16 and then through the resistor 22 and the emitter 18 optocoupler 21 to the input unit 14 matches. However, due to optical feedback through the optocoupler 9 with the emitter is the source of the transistor 2 negative cut-off voltage. Then both input unit 14 matches will be a logical unit, to the input of the pulse shaper management 6 receive the enabling signal and turns on the power transistor 3. Next, the processes are repeated, and the algorithm switching Converter provides the setting in resonance with an absolute error less time resorption static induction transistors 2, 3. When the power is variable over a wide range of constant voltage or pulsed supply voltage the operating principle of the Converter according to p. 2 consists in the following. Run the Converter is the same as the run when the power supply stable power voltage. Let the mode Converter was installed and optical feedback in conjunction with the block of automatic frequency provided a resonance in the load. When unlocking a field-effect transistor 26 to the gate of the power transistor 2 is set to a positive current from voltage source 32 through isolation diode 31, forcing the capacitor 27 discharges through the input circuit of the power transistor 2, providing fast start-up for small values of the power voltage. Through a resistor 25 and a cut-off diode 23 from block according to the Institute of economy and management. Shut the diode 31 is locked and the gate of the power transistor is set to a current proportional to an output current. When switching the output unit 15 matches from a single state in zero field-effect transistor 26 is locked, and a field-effect transistor 29 is unlocked, the gate of the power transistor 2 is set to the locking current from voltage source 34 through isolation diode and through discharge forcing capacitor 30. For sufficiently large values of the power voltage cut-off diode 33 is closed and the locking current proportional to an output current supplied from the block matching 7 cutting through the diode 23 and the resistor 28. When the switching power transistor 3 are going through similar processes. As a result of lower losses in field-effect transistors 26, 29, and power transistors of the inverter and increases the efficiency of the Converter. Also increases the efficiency of heat due to the increased accuracy of the matching of the load and the Converter. Increases the reliability of the Converter due to the disappearance of through currents and providing switching at zero current or voltage. 1.
