    摘要: A power supply apparatus in which a full-wave rectifier is connected to an A.C. power source, a load circuit as a parallel circuit of a smoothing capacitor connected in parallel to a load is connected to outputs of the full-wave rectifier through a switching element and a capacitor, and a control means for adjusting a voltage across the capacitor is provided in parallel to the capacitor to cause a sum of voltages across the capacitor and smoothing capacitor to be proportional to an input voltage and to cause a voltage corresponding to a difference between the input and output voltages to appear across the capacitor to apply a desired constant voltage to the load, whereby an envelope line of an input current becomes proportional to the input voltage under control of switching elements. Thereby power conversion can be realized with use of a small number of switching elements, the arrangement of a control circuit can be simplified, and a peak current at the time of adjusting the voltage across the capacitor can be made small.
