摘要
A soft-switching and low input current ripple power inversion circuit, in which the inversion circuit is connected in parallel to an input DC voltage source and includes a top cell, a bottom cell and at least one transformer, in which the top cell and the bottom cell have its individual impedance adjusting unit of which the impedance can easily be adjusted to obtain the required equivalent resonant inductance or capacitance. Thus, the semiconducting switches therein can be soft-switched alternately to reduce the switching loss. Moreover, the inversion circuit can be modified by adding at least one middle cell inserted between the top cell and the bottom cell to reduce the voltage stress on the semiconductor switch. Consequently, low voltage rating semiconductor switch accompanied with lower RDS(on), conduction losses can be reduced to improve the converter efficiency.
