Abstract:
In a direct AC to AC power increasing apparatus for connection with an AC receptive load and with an input power source supplying an AC input voltage, the improvement comprising:a voltage source chargeable by said AC input voltage,a polarity reversing energy storage means in circuit with said voltage source for supplying an AC signal to a resonant circuit means,said series parallel resonant circuit consisting of an inductor connected in series with a series capacitor and in series with a parallel capacitor which in turn is parallel to the load, andthe values of said series and said parallel capacitors determining the dominance of the series and parallel capacitors,an electronically controlled high frequency switch in circuit with said polarity reversing energy storage means wherein a polarity reversal occurs responsive to opening and closing said electronically controlled high frequency switch wherein said polarity reversing energy storage means acts as a switching element,said polarity reversal, causal to supplying an AC voltage signal to a resonant circuit means for electrical connection with the AC receptive load, andsaid resonant circuit means generating a high frequency AC voltage in response to said AC voltage signal, and further controlling a level of power supplied to the AC receptive load in response to said electronically controlled high frequency switch.
