<P>PROBLEM TO BE SOLVED: To provide an insulated converter capable of preventing a transformer from being bias excitation, without having to use a large-capacitance capacitor for preventing bias excitation. <P>SOLUTION: This insulated converter has a DC power supply, the transformer, an excitation circuit that uses the DC power supply for exciting a primary winding of the transformer into positive and negative, and a measurement circuit for measuring the excitation current that flows in the primary winding. <P>COPYRIGHT: (C)2010,JPO&INPIT |
