The controller can perform chopper control for cyclically turning on and off the switch in accordance with a PWM signal. Where an electromotive voltage of the dynamo is lower than a charged voltage, a boosted voltage can be produced by chopper amplification. If the electromotive voltage is low, it can be charged in the charging portion if the boosted voltage is increased to a sufficient level prior to charging.Field of SearchWith supplemental power sourceWith power monitor POWER SUPPLY DETAILS Electrical Solar cell Using choke and switch across source Switched (e.g., switching regulators) With reference voltage circuitry With ramp generator or controlled capacitor charging With electron tube or valve as control means in the line circuit With transistor control means in the line circuit Transistor CAPACITOR CHARGING OR DISCHARGING For large capacitance (e.g., "super" capacitor, memory backup capacitor, etc.) WIND, SOLAR, THERMAL, OR FUEL-CELL SOURCE With shuntless charging source control | |
