The present application relates to the technical field of
electricity, and especially relates to a power element topology circuit, which comprises a multi-stage
decoupling capacitor loop, a
semiconductor switch module and at least two pins; the multi-stage
decoupling capacitor loop is connected with the
semiconductor switch module; the
semiconductor switch module comprises at least two switches; the at least two pins are short-circuited between the at least two switches, and are used for providing a current flowing function in the case that the semiconductor switch module is turned on. The problem of fast power switch loss can be solved. Due to the current flowing effect of the at least two pins, the
inductance in the turned-off loop in the semiconductor switch module is reduced, and then the peak
voltage in the loop can be lowered, the safety of a working
system in which the power element is located during working is improved, the high-frequency
electromagnetic interference is inhibited, the
inductance in the turned-on loop in the semiconductor switch module is larger than that in the turned-off loop, and the loss of the switch in the semiconductor switch module can be reduced.
