Abstract
An LLC converter includes a switch module, a transformer, an output circuit, a resonant circuit and a safety capacitor. The switch module is connected between an input voltage and a ground. The transformer has a primary side winding and at least one secondary side winding. The output circuit is connected between the at least one secondary side winding and a load. The resonant circuit is coupled between the primary side winding and the switch module and includes at least one leakage inductor. The safety capacitor is connected between the at least one leakage inductor and the switch module.
