What is the principle of Kehua series resonant if power supply
1. The output voltage of Kehua series resonant intermediate frequency power supply is similar square wave, which is because the frequency of the circuit is between the resonant frequency, which can make the oscillating circuit produce the minimum impedance for the fundamental wave. Therefore, when the load current is near, the sine wave can be realized at the same time. By avoiding the direct connection between the upper and lower bridge arms of the inverter, the commutation must be conducted after the switch off. When the switch off and There must be enough dead time in the conduction room.
