Claims

[Scope of utility model registration request]

A first transformer 1 that rectifies and smoothes an AC power source and converts it into a DC power source.
In a switching power supply, a secondary winding and a switching transistor are connected in series to a DC power supply, and the switching transistor is turned on and off to supply power to the secondary side through the first transformer.
A transformer for a switching power supply, characterized in that part or all of the secondary winding and the secondary winding are heat-resistant insulated wires. 1
