Schaltkreis zur Regulierung der Spannung, insbesondere für eine Ladepumpe

摘要

The device has a voltage regulator (RGCT) for regulating a high voltage (Vpp) provided by a booster circuit (HVCT). An inverter (I1) stops or activates the circuit based on whether the voltage is higher or lower than a reference voltage. The regulator has a step down transformer circuit (E2) and a voltage limiting circuit (E3) having a threshold voltage higher than the reference voltage for clipping a surge voltage, appearing in the high voltage, higher than the threshold voltage. An independent claim is also included for a method of regulating a direct voltage provided by a voltage generator.
