摘要: A switched-mode power supply for producing a DC voltage output from unidirectional-current or alternating-current input uses amplitude modulation of current through and inductor. Input terminals joined to the inductor receive input. switch in series connection with responds switching signal controlling current. capacitor diode store energy received computation circuit is control sensing opening when reaches desired maximum. reference generator, which produces indicative maximum current, includes an adjustment modulating error signal, derived integral difference between actual voltage, by voltage. Inductor thereby modulated phase quick response provided rapid fluctuations An alternating source resonant oscillator having substantially pure sine wave output. thermally-activated safety also absorbing high surges appear on supply.
