Abstract: An isolated converter with high boost ration includes a transformer, a first bridge arm, a second bridge arm, and a boost circuit. The transformer includes a secondary side having a secondary side first node and a secondary side second node. The first bridge arm includes a first diode and a second diode. The second bridge arm includes a third diode and a fourth diode. The boost circuit includes at least one fifth diode coupled between the first bridge arm and the secondary side second node, at least one sixth diode coupled between the second bridge arm and the secondary side first node, and at least two capacitors coupled to the secondary side first node and the secondary side second node.

Abstract: A bidirectional power factor correction (PFC) module is coupled to an AC power source, an energy storage unit, and a DC bus. The bidirectional PFC module includes a bridge arm assembly and a control unit. The bridge arm assembly includes a first bridge arm, a first inductor, a second inductor, and a second bridge arm. The control unit provides a plurality of control signals to control the first bridge arm and the second bridge arm to make the bidirectional PFC module operate in an AC power supply mode, a DC power supply mode, or a power feed mode.

Abstract: An inverter apparatus with overcurrent protection control includes a first terminal of a DC input terminal connected to an AC output terminal through a first switch element and a second switch element, and a second terminal of the DC input terminal connected to the AC output terminal through a fourth switch element and a third switch element. An intermediate potential terminal is connected to a fifth switch element and a sixth switch element, and connected to the AC output terminal through the fifth switch element and the second switch element, and connected to the AC output terminal through the sixth switch element and the third switch element. When the control unit determines that the inverter apparatus is in an overcurrent state, the control unit controls a sequence of turning off the inverter apparatus to be the second switch element, the first switch element, and the sixth switch element.
