Electrical energy conversion systems

摘要: Electrical circuits, apparatus and methods for a variety of applications. A switching device subdivides an alternating current input signal into plurality lower voltage pulses by on off in response to the characteristics, such as current, signal, are intermittently passed capacitor series with is positive-going. When becomes negative-going, discharged, usually passing through switch opposite direction. Work done energizing capacitor, or parallel switch, inductor relation combination above. The may be primary winding transformer, create electrical magnetic field which transduced mechanical motion. load also resistive load. Where tranformer provided, output secondary used power supply, without additional filtration. transformer have unity turns ratio, step up down desired. other applications, direct provided can very carefully controlled minimum circuitry being necessary accomplish this purpose.
