  • Positive-negative pulse type high frequency switching power supply unit
    Patent number: 6130831
    Abstract: The invention provides a positive-negative type high frequency switching power supply unit which provides a high frequency output of an ideal sine waveform to allow reliable switching with very low switching loss without being influenced by a leakage inductance of the load side, a parasitic capacitance and a parasitic inductance produced by a wiring line or the like, and a load condition.
