What is a high voltage inverter?
Typically, they are on the high voltage side (from 30 kV to 150 kV and more), and are made by connecting back-to-back controlled rectifier and inverter employing a DC bus. Dealing with high voltages, classical bridge rectifiers, and two-level inverters are not suitable due to the limited characteristics of electronic switches.
How does a high-voltage full bridge inverter work?
A high-voltage full bridge inverter works by converting the DC voltage V1 to a high-frequency square wave AC voltage. This AC voltage is then supplied to a 20kHz frequency high-voltage transformer T1, which, after the boost rectifier, provides power to the load. The inverter high-voltage full bridge drives the routing components and the IGBT power modules.
