REGULATOR FOR MICOM

摘要

A regulator for a micom is provided to reduce the power dissipation of the regulator and improve the power factor approved to the micom. A diode(D) is coupled to an anolyte terminal in an inputting terminal of a common alternating current. A switching unit(10) is connected to a cathode terminal of the diode. A PWM(Pulse Width Modulation) controller(14) is connected to the switching unit and supplies a pulse width modulation signal to the switching unit. A serial regulator(12) is connected to the cathod terminal of the diode and provides a driving power to the micom in initial operation. A capacitor(C) is connected to the switching unit and the serial regulator.
