TRANSFORMER MODULE AND DC-DC CONVERTER DEVICE

摘要

PROBLEM TO BE SOLVED: To suppress generation of circuit malfunction or power loss in a device with a transformer and a current transformer for detecting an electric current running through a primary winding thereof.

SOLUTION: A transformer module 4 comprises a transformer 20 having a primary winding 21 and a secondary winding and a current transformer 60 for measuring an alternating current (AC) running through the primary winding 21 of the transformer 20, and is configured so that a leading wire section 27A of the primary wiring 21 is used as a primary winding 61 of the current transformer 60.
