<p>PURPOSE:To reduce the ripple current by providing a phase difference in the ON and OFF operations of a semiconductor switch of a plurality of switching regulators connected in series at the input side and connected in parallel at the output side. CONSTITUTION:The input sides of four sets of switching regulator circuits 20, 30, 40, 50 are connected in series, and the output sides are connected in parallel for all four sets. The circuits 20, 30, 40, 50 are divided into two groups of two sets of the switching regulator circuits 20, 30 and 40, 50, and ON and OFF are controlled by the phase difference of 180 deg. at the transistor switch in the switching regulator circuits of the respective group.</p> |
