Abstract
According to the switching supply such as a DC/DC converter, since primary side coils provided in two transformers are mutually connected in series, voltage variation generated in parallel-connected secondary side coils can be suppressed, and the uniformity of secondary side parallel output can be enhanced even in case of voltage value fluctuations or the like caused by variation in the output of an inverter circuit.
