cshf series of high-voltage inverter system uses multi-level cell tandem technology, a high - high voltage source inverter, direct 3,6,10kv input directly 3,6,10kv high voltage output. drive from the main phase-shifting transformer, the power module and the controller.
each phase of the output of the power unit adjacent to each other in series, according to the three-phase y-connection is connected to achieve vvvf high-pressure direct output, the supply of high-voltage motors. through each power unit of the pwm output waveform phase shift superposition can get stepped sinusoidal pwm waveform. each power unit on the structure and electrical properties of exactly the same, interchangeable.
