ABSTRACT:
Conventional power supplies that actify the grids of electric rockets use an output capacitor to smooth the output DC voltage signal. Large capacitors tend to store a great amount of energy. Arcing acts to transfer this energy to create a well or pit on an accelerator grid of the electric rockets that may eventually cause repeating arcing or perforation on the accelerator grid. Various embodiments of the present invention eliminate or reduce the need to use an output capacitor. Additionally, various embodiments of the present invention use multiple phases of an input signal into the power supply to cause the output DC voltage signal to be substantially smooth.
