Abstract
A DC power supply apparatus includes a switching transformer having a switching element, a primary current detection circuit, arranged on a primary side of the transformer, for detecting a current flowing in the switching element, a secondary current detection circuit for detecting an output current from a secondary side of the transformer, and a control circuit for controlling the switching element on the basis of outputs from the primary and secondary current detection circuit.
