<p>PURPOSE:To provide economical and lightweight device by using common control signal to control multiple PWM converter. CONSTITUTION:On a power converter, AC voltage (VSO) from AC power supply 3 is applied to the transformer 4, on which to the devided two secondary winding 4A-4B of its secondary, the converter 1-2 are connected each other through the reactor 5-6 respectively. The DC terminal of the converter 1-2 supply DC voltage (Vd) through the smoothing capacitor 7 to the load 8. The deviated signal of DC voltage (Vd) is given to the voltage regulator 9 and becomes the reference signal of peak value (Im). On the other hand, AC voltage (VSO) is added to synchronizing signal generator 10, converted to the synchronizing signal (SY), given to the multiplier 11 and becomes input current reference signal (IS). Furthermore, the gate signal for convertor 1-2 is generated by adding this deviated signal to the current regulator 12 and converting to the voltage reference (eil) and through the carrier generator 13, 16 and the gate circuit 14, 17.</p> |
