Abstract
A switching power supply causes fewer losses, being capable of suppressing surges generated at a switching element, and providing improved conduction noise characteristics. The present invention is a switching power supply, wherein voltages and currents are varied by turning said switching element on and off to convert input voltages into output voltages, comprising a distributed parameter line with a line length of about(n is an integer of one or more) of a wavelength peculiar to a potential point at said fluctuating potential point in said switching power supply.
