MCCB(Molded Case Circuit Breaker) is widely used in power distribution systems for protecting an electrical circuit from damage caused by overload or short circuit. The shunt release device, an internal accessory of MCCB, opens the mechanism in response to an externally applied voltage signal. The shunt release device consists of an actuator and a control circuit. The conventional shunt release device...
In this paper, we present a new charge pump circuit feasible for the implementation with standard twin-well CMOS process technology. The proposed charge pump employs PMOS-switching dual charge-transfer paths and a simple two-phase clock. Since charge transfer switches are fully turned on during each half of clock cycle, they transfer charges completely from the present stage to the next stage without...
