[0002] A frequency of 20KHZ to 400KHZ is widely used in semiconductor, solar photovoltaic, industrial coating, plasma cleaning, nanomaterial processing, material surface modification and other industries The sine wave high-power power supply, in order to meet the requirements of the above-mentioned industrial equipment, adopts a switch hybrid resonant circuit and a switch hybrid resonator to convert the square wave output by the previous switch circuit into a sine wave with small harmonic components and low spurious noise. The output power of the required power supply is thousands to tens of kilowatts. In the existing switching hybrid resonant circuit and switching hybrid resonator, the switching power tube, the inductor, capacitor and transformer in the hybrid resonant circuit will bear a large current and power. At the same time, switching power transistors, resonant inductors, capacitors and transformers at all levels and the connections between the levels flow dozens of hundreds of amperes of high-frequency current, which causes the circuit to generate large peak interference and heat, and is also prone to harmonics. Interference, thus affecting the normal use of the circuit

Switching power transistors, inductors, capacitors, transformers and other components in the existing switching hybrid resonators are often due to problems with the installation structure, and the wiring of the components between the levels is messy, resulting in unstable power output waveform frequency, and the components are easy to burn out
