Abstract
A switch circuit package module includes at least a semiconductor switch unit and at least a first capacitor unit. The semiconductor switch unit includes a first semiconductor switch element and a second semiconductor switch element. The first semiconductor switch element and the second semiconductor switch element include a plurality of sub micro-switch elements. The capacitor unit includes a plurality of capacitors configured to cooperate with the sub micro-switch elements. The capacitors are arranged in a symmetrical distribution surrounded the semiconductor switch unit, such that impedances of any two symmetrical commutation loops each of which mainly consists of one capacitor and two sub micro-switch elements from the first semiconductor switch element and second semiconductor switch element respectively are close to or the same with each other.
