Abstract: The continuous conduction mode (CCM) boost voltage power factor correction apparatus with an average-current control mode of the present invention uses resettable integrators to integrate the difference voltage signal outputted from the voltage error amplifier and the input current signal obtained from detection. The integration results are then compared to control the duty cycle of the switch. Thereby, the input current and the input voltage in the AC/DC electrical power converter have a proportion relation and their phases are the same as each other. The components used in this control method are simpler than the PFC circuit of the prior art. It is easy to integrate in one chip with fewer pins. The apparatus of the present invention has a high power factor and a low total harmonic distortion (THD).

Abstract: A high-speed, solid-state circuit breaker is capable of interrupting high DC currents without generating an arc, and it is maintenance-free. Both the switch and the tripping unit are solid-state, which meet precise protection requirements. The high-speed, solid-state DC circuit breaker uses an emitter turn-off (ETO) thyristor as the switch. The ETO thyristor has an anode, a cathode and first, second and third gate electrodes. The anode is connectable to a source of DC current, and the cathode is connectable to a load. A solid-state trip circuit is connected to the first, second and third gate electrodes for controlling interrpution of DC current to the load by turning off said ETO thyristor.
