HIGH VOLTAGE FREQUENCY CONVERSION POWER SUPPLY DEVICE

摘要

A high voltage frequency conversion power supply device comprises a high voltage incoming cabinet and a transformer. A high voltage cable enters the high voltage incoming cabinet, and leaves same and enters the transformer. The high voltage incoming cabinet is provided with several stages of current limiting resistors. The transformer is connected to an inverter by the high voltage cable. The inverter is formed by several PWM power units connected in series or in parallel. The inverter is connected to a sinusoidal filter by the high voltage cable. The sinusoidal filter is connected to a high voltage outgoing cabinet by the high voltage cable. The high voltage frequency conversion power supply device is further provided with a PLC programmable controller. The PLC programmable controller is connected to the inverter by a signal line. The high voltage frequency conversion power supply device is of a more reasonable structure, stable, and convenient for use and control, and can effectively realize high voltage frequency conversion output.
