High voltage stabilized power source

Abstract

Abstract PURPOSE:To stabilize a power source of large capacity inexpensively by connecting the stabilized first DC power source in series with the non-stabilized second DC power source to stabilize the output by absorbing by the first power source the variation of the voltage. CONSTITUTION:An AC power source is regulated by a circuit 1 at the input, the voltage is raised by a 3-phase transformer 2, rectified by a full-wave rectifying circuit 3, a negative terminal is earthed, and a positive terminal P is connected to the negative terminal of another rectifying circuit R. The circuit R generates a high frequency voltage by rectifying the voltage of the AC power source by the full-wave rectifier 3' in a circuit of a switching element 8, a transformer 6 and a gate circuit 11 into a DC through a transformer 12 by the rectifier 3'', the positive terminal is connected to the power source +Ebb, and the negative terminal is connected to the point P. The total output voltage +Ebb is detected by a voltage divider 13, compared by a comparator 10 with a reference voltage, and a gate circuit 11 is controlled by the output. In this manner, the general output voltage +Ebb is stabilized by the stabilized power source of small capacity, thereby reducing the facility cost.
