Abstract

A DC-to-AC power conversion system is provided to convert a DC input voltage (Vdc) into an AC output voltage (Vac), which mainly includes a bridge switching circuit (12), an auxiliary switch circuit (13), and a control circuit (15). The bridge switching circuit (12) has a first power switch (S11), a second power switch (S12), a third power switch (S13), and a fourth power switch (S14). The auxiliary switch circuit (13) has a fifth power switch (S15), a sixth power switch (S 16), a seventh power switch (S 17), and an eighth power switch (S 18). The control circuit (15) produces a complementary switching signal pair (Sc1, Sc4 and Sc2, Sc3) to control the first and fourth power switches (S11, S 14) and the second and third power switches (S12, S13), respectively. In addition, the control circuit (15) produces a complementary level signal pair (Sc6, Sc7 and Sc5, Sc8) to control the sixth and seventh power switches (S16, S17) and the fifth and eighth power switches (S 15, S 18), respectively.
