发明名称 Power converter, control method of power converter, and hard disk drive
摘要 A power converter includes a first inductor, a rectifier arm, a first switch arm including a first and second switch circuits, a second switch arm including a third switch circuit and a first capacitor, a LC serial circuit, a Transformer, a rectification and smoothing circuit connected to secondary winding of the transformer, and a control circuit to perform on-off control of the three switch circuits. The rectifier arm, the first and second switch arms and the LC serial circuit are connected in parallel with each other. The LC serial circuit and primary winding of the transformer are connected. AC power supply is connected to the rectifier arm via the first inductor. The control circuit includes an output voltage control circuit to control output voltage at specific setting value, an intermediate voltage control circuit to control intermediate voltage at specific setting value, and a power factor correction control circuit.
