Inverter power supplyThe reverse process of converting direct current into alternating current using a thyristor circuit, which corresponds to rectification, is defined as inversion. For example, in an electric locomotive using thyristors, when going downhill, the DC motor is used as a generator to brake and convert the locomotive's potential energy into electrical energy, which is then sent back to the AC power grid. For example, if a running DC motor needs to brake quickly, it can also be operated as a generator, converting the motor's kinetic energy into electrical energy and sending it back to the power grid. Principle of inverter power supplyThe circuit that converts direct current into alternating current is called an inverter circuit.
