Abstract
PURPOSE:To control a DC power device at a designated voltage value, by taking out a synchronizing signal from a separate winding of a transformer and by synchronizing switching operation without recourse to an operating frequency. CONSTITUTION:A DC power device converts the power supplied from a primary power source 1 into pulsatile power with a switching element (a) 7 and inputs it into a transformer (a) 9. With this transformer (a) 9 the power is converted into what is stepped down (stepped up) up to the prescribed voltage, and is applied to a load (a) 13 as DC output with a rectification-smoothing circuit (a) 11. This voltage is detected through a voltage detection circuit (a) 12 and the pulse width is controlled with a pulse width control circuit (a) 10. On this occasion, the output signal of a transformer (b) 19 of a DC power device 5' in system (b) is inputted into a waveform rectification circuit 25 and this signal analoguous to the switching waveform of a swtiching element (b) 18 can be obtained even if the operational frequency gets high. The output voltage can thus be controlled at a fixed value by supplying the synchronizing signal from the separate winding of the transformer even if the operational frequency gets high.
