Abstract
A DC-to-AC power conversion system is provided to convert a DC input voltage into an AC output voltage, which mainly includes a bridge switching circuit, an auxiliary switch circuit, and a control circuit. The bridge switching circuit has a first power switch, a second power switch, a third power switch, and a fourth power switch. The auxiliary switch circuit has a fifth power switch, a sixth power switch, a seventh power switch, and an eighth power switch. The control circuit produces a complementary switching signal pair to control the first and fourth power switches and the second and third power switches, respectively. In addition, the control circuit produces a complementary level signal pair to control the sixth and seventh power switches and the fifth and eighth power switches, respectively.
