Power supply system and power converter with start circuit for boost modules
A power supply system includes multiple power converters. The output terminals of the power converters are coupled to each other. The power converter includes a rectifier unit, a first boost module, a start circuit, a second boost module, a first switch and a control unit. The control unit is electrically coupled to the rectifier unit, the first boost module and the first switch. After the second boost module receives the third voltage, a fourth voltage is delivered by the first switch from the second boost module to the first boost module. When the control unit receives the first voltage for a predetermined time, the control unit turns off the first switch and stops outputting the fourth voltage to the first boost module.
