Claims

[Scope of utility model registration request]

The pulse width has a primary winding, a secondary winding, a control winding, and an auxiliary power supply winding for control, and the pulse width of the output voltage of the secondary winding can be controlled by flowing a control current through the control winding. A control transformer, a converter □ that supplies an output to the primary winding of the pulse width control transformer, and a converter that uses the output obtained from the control auxiliary power winding as a power source, and that controls fluctuations in the output voltage of the secondary winding. In the device, the primary winding is divided into a first winding and a second winding and is wound around a magnetic core, and the control circuit detects the A stabilized power supply device characterized in that the auxiliary power supply wire is wound in an overlapping manner across each divided winding of the primary winding.
