Efficiency Improvement of Synchronous Buck Converter by Passive Auxiliary Circuit
IEEE Transactions on Industry Applications, 2008This paper proposes a zero-voltage-transition (ZVT) pulse width modulated (PWM) synchronous buck converter, which is designed to operate at low voltage and high efficiency typically required for portable systems. A new passive auxiliary circuit that allows the main switch to operate with zero-voltage switching has been incorporated in the conventional ...

Externally-fed auxiliary power supply of MMC converter cells
2016 18th European Conference on Power Electronics and Applications (EPE'16 ECCE Europe), 2016We designed an auxiliary power supply for medium voltage MMC-converters with system voltages up to 36 kV rms . The system supplies up to 250 W power and is based on a two-stage design. The first stage is an inductive power transfer system that isolates against the system voltage. It is connected to a low voltage DC-supply on ground potential, and shows

Power auxiliary resonant commutated pole converters for utility applications
Proceedings of the IECON'97 23rd International Conference on Industrial Electronics, Control, and Instrumentation (Cat. No.97CH36066), 2002The auxiliary resonant commutated pole converter has the ability to improve the performance of the hard switched converter for utility applications at the distribution power level. Low complexity and modularity are achieved by using integrated active snubber modules with conventional IGBT modules.
