Abstract: A high voltage DC power supplier includes: a transformer driven by a switching device, transforming an input voltage to a certain level of high voltage, and outputting the transformed high voltage; a diode and a capacitor for rectifying and smoothing the high voltage outputted from the transformer, and supplying the smoothed voltage to an ER fluid application unit; a discharge circuit for forcibly discharging the output voltage when an output voltage of the capacitor descends; and a controller for controlling a turn-on operation of the switching device on the basis of a difference value between the output voltage and a reference voltage so that the output voltage can follow a target voltage, and outputting a control signal for driving the discharge circuit to the discharge circuit when it reaches a discharge period.

Abstract: PURPOSE: A circuit for controlling a discharge of a high-voltage DC(Direct Current) power supplier is provided to improve the control property by adding a discharge circuit to an output terminal of a flyback converter to discharge rapidly a voltage stored in a capacitor. CONSTITUTION: A transformer(T1) is driven by a MOS transistor(M1) which is a switching device to convert an input voltage(Vs) into a predetermined level of a high voltage and output it. A diode(D1) and a capacitor(C1) rectify and smooth the high voltage outputted from the transformer(T1) to supply it to an ER(Electro-Rheological) fluid application equipment. When an output voltage(Vo) of the capacitor(C1) drops, a discharge circuit(2) discharges rapidly the output voltage(Vo) by force. A controller(4) controls a turn-on operation of the MOS transistor(M1) based on an error component of the output voltage outputted from a subtractor(3) and outputs a control signal for driving the discharge circuit(2) at every time when reaching to a discharge period.
