The high-voltage inverter converts direct current (DC) from the batteries or generator to alternating current (AC) to power the drive motors.
The high frequency power inverter includes two parts, main circuit and control circuit. The main circuit includes an inverter DC power supply, high frequency high voltage transformers, IGBT bridge inverter, protection circuits, high frequency high voltage silicon stack (Rectifier) , etc. The control circuit includes a current, voltage sampling and processing unit, driver circuit, PWM signal generation, micro-controller, keyboard and LCD parameter input, part of the communications interface.
This high frequency power inverter let the whole system has a complete user interface and intelligent characteristics such as self-diagnosis.
