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 1 n 4 (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.
Claims11
A switching power supply, wherein voltages and currents are varied by turning a switching element on and off to convert input voltages into output voltages, comprising a distributed parameter line at a fluctuating potential point in said switching power supply and having a line length of about
- 8 n 4
- (n is an integer of one or more) of a wavelength peculiar to said potential point.
A distributed parameter structure of a distributed parameter line, which branches off at a main line and separates specific frequency elements of signals propagating on said main line, wherein said distributed parameter line is formed in a winding structure or in a folded structure.
A distributed parameter structure of a distributed parameter line, which branches off at a main line and separates specific frequency elements of signals propagating on said main line, wherein said distributed parameter line and a stable potential line connected at a stable potential point are arranged adjacently, while said distributed parameter line and said stable potential line are formed in a winding structure or in a folded structure.
