AI Technical Summary
Existing multilevel inverters suffer from insufficient voltage gain and complex circuit structure. In particular, traditional single-phase seven-level inverters fail to meet the high-efficiency requirements in terms of output voltage gain and number of components.
A boost-type five-level inverter with double voltage gain is adopted, which includes two switched capacitors, one inductor and four pairs of complementary conducting switching transistors. By using different combinations of switching transistors and control strategies, five-level voltage output is achieved, simplifying the circuit structure and improving the voltage gain.
It achieves a five-level, double voltage boost gain, has a simple circuit structure, automatically balances the voltage of the switched capacitors, has a small charging pulse current for the switched capacitors, and offers a flexible control strategy.
