Abstract
A DC voltage from a DC supply is applied to inverters of two power supply units connected in parallel with each other. The inverters convert the received DC voltages into high-frequency voltages, which are, in turn, voltage-transformed in transformers. The outputs of the transformers are rectified in two rectifiers, respectively, and smoothed in two reactors. The smoothed voltages are supplied between output terminals. The reactors are formed on a single core, being loosely coupled with each other.
