Abstract: A power converter includes a full-bridge converter circuit and a regulation circuit. The full-bridge converter circuit includes a full-bridge circuit having a first and a second input terminals and a first and a second output terminals. The regulation circuit is bridged across the first and the second input terminals of the full-bridge circuit and connected to the first output terminal of the full-bridge circuit. The regulation circuit is configured for operatively regulating an output voltage across the first and the second output terminals of the full-bridge circuit by cooperating with the full-bridge converter circuit, such that the output voltage across the first and the second output terminals of the full-bridge circuit has more than three voltage levels. A method for controlling a power converter is also disclosed herein.

Abstract: The present invention discloses an inverter and a control method thereof. The inverter includes a first bridge leg having a series of first switch, second switch, third switch, fourth switch and fifth switch, and a second first bridge leg having a series of sixth switch, seventh switch, eighth switch, ninth switch, tenth switch. The control method includes steps of synchronously turning on or off the first switch, second switch, ninth switch and tenth switch, controlling that an on/off state of the third switch or eighth switch is complementary to an on/off state of the first switch, second switch, ninth switch and tenth switch, and synchronously turning on or off the fourth switch, fifth switch, sixth switch and seventh switch.
