Claims

[Claims for Utility Model Registration] A quasi-E miswitching regulator that converts direct current into alternating current using a high-frequency inverter, transforms it using a transformer (and then rectifies it to obtain direct current, which is supplied to a load). A quasi-E class switching regulator characterized in that the primary and secondary windings of the switching regulator are arranged separately to increase the leakage inductance of the truss.
