FIELD: electricity.
SUBSTANCE: power supply source for magnetron includes high-voltage converter (101), microprocessor (103) and resistor (109). High-voltage converter comprises integrated-circuit oscillator IC1, switching transistors T1, T2, inductance coils LI, transformer (106) and rectifier (107). Power supply source (4) supplies high direct-current voltage to converter (101). Made as error signal amplifier with integrating capacitor C7 and resistor R9 operational amplifier (122) compares control signal from microprocessor (103) and resistor (109) and supplies output signal to oscillator IC1. Oscillator IC1 controls switching transistors T1, T2, which output is connected to inductance coil LI and primary winding of transformer (106). Secondary winding of transformer (106) is connected to diodes D3, D4, D5, D6 of half-bridge and capacitors C5, C6, which deliver direct current from transformer to magnetron (102).
EFFECT: higher control accuracy.
