Abstract
A switch circuit electrically connected to a power source and a first control source and including a plurality of switch bridge arms is provided. Each of the plurality of switch bridge arms includes a first switch and a second switch electrically connected in series. A loop formed by the first switch, the second switch and the power source is defined as a power loop. A loop formed by the first control source and the first switch is defined as a first control loop. A first mutual inductance is formed between the power loop and the first control loop. Among all the first switches, the first switch with the longer power loop has the smaller first mutual inductance.
