Abstract
PURPOSE: To reduce surplus electric power to improve the conversion efficiency, by comparing phase information corresponding to current change of the load with the reference phase and by driving the switch part, which supplies electric power to the load, by the comparison output.
CONSTITUTION: DC current fluctuation due to fluctuation of load 7 is detected by level converter 5 and is transferred to phase control oscillator 6, and the output of oscillator 6 is given to phase comparator 2. Comparator 2 compares the output of reference frequency oscillator 1 and the output of oscillator 6 with each other in phase and outputs DC fluctuation components of load 7 as the phase difference. After subjected to level conversion in level converter 3, the phase difference is rectified to a DC voltage by LPF4 and is supplied to load 7. Consequently, the current supplied to load 7 is made constant. By this system, electric power is supplied to the load at 100%, and surplus electric power becomes zero.
