Title: Multi-input multi-output converter
Inventor: KOYASHIKI TOORU
IPC: H02M3/28
Filed: 1984-04-12
Abstract: PURPOSE:To reduce the size of a power source which occupies in the entire converter by detecting the voltage of a DC power source, and setting a switch which converts the conduction and the nonconduction of a load current to the nonconduction when the detected voltage is not normal. CONSTITUTION:The first DC power source 1 is obtained by rectifying a commercial power source. The second DC power source is a battery 11.
