Abstract

A bridge circuit and a short-circuit protection method thereof. The bridge circuit includes an input power unit, a converter unit, a first capacitor, a second capacitor, a detection unit and a bridge inverter unit. The input power unit includes a first electrode and a second electrode. The converter unit is coupled to the input power unit. The first capacitor includes a first terminal and a second terminal. The second capacitor includes a first terminal and a second terminal. The bridge inverter unit includes a plurality of switches and is coupled to the converter unit, the first capacitor, the second capacitor, the detection unit and the second electrode. The detection unit issues a short-circuit signal to a control unit when the detection unit detects a current variation on the second capacitor.
