ABSTRACT:
The resonant switching power supply circuit comprises positive and negative DC input terminals. First and second switching elements are connected in series between the DC input terminals. Each switching element has a control input for receiving a control signal controlling a duty cycle of the switching element. A first capacitor is connected between the DC input terminals. Second and third capacitors are connected in series between the DC input terminals. A first pair of reverse biased rectifying elements in series is connected between the DC input terminals. Each rectifying element of the first pair is connected in parallel with a respective one of the switch elements. A second pair of reverse biased rectifying elements in series is connected between the DC input terminals. Each rectifying element of the second pair is connected in parallel with a respective one of the second and third capacitors. The circuit also comprises a transformer including a primary winding having opposite winding ends connected between the rectifying elements of the first pair and between the rectifying elements of the second pair respectively, and a secondary winding having opposite winding ends. A pair of output terminals is connected to the winding ends of the secondary winding of the transformer respectively, to supply power. The resonant switching power supply circuit can be used as a power inverter or converter.
