| Abstract: | A push-pull high-voltage generating circuit is introduced, which takes TL494 as a con- trol core, and adopts pulse-width modulation （PWM） and voltage feedback push-pull technologies. It can output a variety of constant DC high-voltage current by adjusting the oscillator frequency and the sampling resistance. The circuit is simple and reliable, and has high stability. The test validation result shows that the circuit can meet the test requirements of insulation resistance in control circuitry of liquid rocket engines |
