Abstract
A power supply circuit having rectifiers and selectable first to n-th power supply voltage terminals for supplying various levels of output voltages. Between respective terminals and an earth, first smoothing capacitors (e.g. C.sub.1 -C.sub.4) are connected. Between i-th terminal and (i-1)-th terminal (wherein, 2.ltoreq.i.ltoreq.n), second smoothing capacitors (e.g. C.sub.5, C.sub.6, C.sub.n, C.sub.n-1) are connected. When i-th terminal is selected, not only capacitance of the first smoothing capacitor connected between the i-th terminal and the earth, but also capacitance of the first capacitor connected between the (i-1)-th terminal and the earth and the second capacitor connected between the i-th and (i-1)-th terminals are utilized for smoothing operation.
