Design of a High Voltage Power Supply for Electrocurtain

The high voltage source of electrocurtain requirements for high power factor, high efficiency, output DC high voltage of low ripple, fast fault response. In order to improve the parameters to design a high voltage source which based on three-phase buck type PWM AC chopper. It has advantages of simple topological structure, fast dynamic response, small ripple, output stability, small peak value. After the test, power supply of the performance indicators has reached the expected design goals, better than the industrial parameters, technical performance can meet the needs of electrocurtain.
