<p>A high-voltage power supply circuit is disclosed that receives ac input, effects rectification and successive multiplication, and outputs a high dc voltage. The high-voltage power supply circuit includes a plurality of diode bridges (11-14; 15-18) connected to secondary winding (3; 7) of the transformer (1; 5) in series by way of capacitors, that effect full-wave rectification of the ac voltage outputted from the secondary winding (3; 7). The high-voltage power supply circuit further includes a plurality of capacitors (C11-C16, C21-C24; C31-C36, C41-C44) provided for each of the diode bridges (11-14; 15-18) that accumulate charges from the output voltage that has undergone full-wave rectification. Voltage that is a multiple of the maximum value of the ac voltage within the secondary winding (3; 7) and the number of stages of diode bridges (11-14; 15-18) (an integer multiple) is outputted at each of the connection points of the diode bridges (11-14; 15-18). <IMAGE></p> |
