The paper objective is to propose an innovative power converter topology combining the advantages of capacitor discharge and switch-mode converters to generate half sinusoidal fast current pulses with high precision. The capacitor discharge operation mode of the converter allows the generation of current pulses with fast transient response and the switch-mode operation enables the control of the pulse...
In this work, four different snubber solutions for an Auxiliary Resonant Commutated Pole (ARCP) converter with an auxiliary thyristor are evaluated. The first two solutions are an RC snubber and a variation thereoff where the RC snubber losses are reduced by employing diodes for limiting the voltage overshoot. Two other concepts are a novel lossless dV/dt clamp snubber circuit and a low-loss RC snubber...
In order to transmit massive amounts of power generated by remotely located power plants, especially offshore wind farms, and to balance the intermittent nature of renewable energy sources, the need for a stronger high voltage transmission grid is anticipated. Due to limitations in AC power transmission the most likable choice for such a grid is a high voltage DC (HVDC) grid. However, the concept...
