Alternative Switch Power Circuitry Systems

摘要: Reliability enhanced systems are shown where an short-lived electrolytic capacitor can be replaced by a much smaller, perhaps film type, longer-lived to implemented in circuits for power factor correction, solar conversion, or otherwise achieve DC voltage smoothing with circuitry that has photovoltaic source (1) input (2) internal device (3) and uses DC-DC converter (4) provide smoothed output (6) substitution (14) may include interim signal (28) creates large variation (16). Switchmode designs first second switch elements (17) (18) alternative path controller (21) operates boost (22) buck (23) duty cycle (32).
