1. Controlling the large power Nowadays, the power transistor can control powers of hundreds of thousands of volt, using the transistor as the switch has many virtues, which are:(1) it's easy to cut off, and it needs a few additional elements; (2) it's fast to switch, and it can work in a high frequency; (3) the withstand voltages of the available elements range from 100V to 700V. Years ago, the switching ability of the transistor is lower than 10kW. Nowadays, it can control powers of hundreds of thousands of volt.2. It directly works on the transistor power switch of the rectified 380V mains
