Abstract

PURPOSE:To provide the subject device using in the source of the device an ACDC - AC - DC inverter wherein after directly rectifying commercial AC, pulses of a frequency higher than the commercial frequency are generated at the power source of said device, and transformed by a transformer so as to be reconverted into DC, thereby to miniaturize the device and produce high efficiency.
