Abstract
PURPOSE: To compensate the delay of chopper circuit control by adding a controllable function at transient time to power inverter.
CONSTITUTION: The main circuit consists of the rectifier 5, the DC filter circuit 2, the chopper circuit 6, the DC filter circuit 7, the inverter 3, and the output transformer 4. In the steady state, the chopper 6 is controlled by the phase signal 16 from the amplification by the error amplifier 15 of the deviation between the output of the output voltage detector 14 and the voltage reference value so as to keep the output voltage constant. In the transient time, e.g., the abrupt change in load, etc., the error amplifier 25 is operated to dispatch the output phase control signal 26 by which the power inverter 3 is operated to control output voltage temporally, displace it with control system for the chopper circuit 6 after 2 to 3 cycles, and transfer it to the transient time control system with the chopper circuit 6 again. Thus, it is possible to prevent the variation in output voltage at transient time due to the response delay of DC controller.
