A Novel Control Scheme Of DCM Boost PFC Converter

A Novel Control Scheme of DCM Boost PFC Converter Abstract The discontinuous current mode boost power factor (PF) correction converter features a zero-current turn-on for the switch, no reverse recovery in diode, and constant frequency operations. However, when the duty cycle is constant in a line cycle, the input current contains rich third harmonic which […]


Technical Assessment Of Load Commutation Switch In Hybrid HVDC Breaker

Technical Assessment of Load Commutation Switch in Hybrid HVDC Breaker Abstract The development of a large-scale high-voltage direct current (HVDC) power grid requires a reliable, fast, and low-loss circuit breaker. The load commutation switch (LCS) is an essential part of ABB’s 1200-MW hybrid HVDC breaker concept, which builds up a low-loss conducting path for the […]
