Abstract

PURPOSE: To supply numerous power outputs with high efficiency through a simple circuit, by providing a smoothing reactor with secondary windings and supplying power outputs from the secondary windings except for a main load.
CONSTITUTION: A power supply device comprises a switching element Q, a commutation diode CR1, a smoothing reactor L, a smoothing capacitor C1, and a detection unit D which compares an output voltage with a reference voltage to control the switching element Q. The smoothing reactor L is provided with secondary windings N2, N3 corresponding to the number of needed power outputs. The windings N2, N3 are connected to other capacitors C2, C3 through other diodes CR2, CR3. The power outputs can be obtained from the terminals of the capacitors C2, C3. If the current of a power output for a main load is large and those of the other power outputs are small, enough stabilization is effected and these three outputs can be supplied with high accuracy through the single switching element.
