In this paper, a novel proposal of the utility-interactive three-phase soft commutation sinewave PWM power conditioner with an auxiliary active resonant DC-link snubber is developed for the fuel cell and the solar power generation systems. The prototype of this power conditioner consists of a PWM boost chopper cascaded three-phase power conditioner, a single two-switch auxiliary resonant DC-link snubber...
A new implementation of a non-isolated, two-inductor, two-switch boost converter topology that features a common ground for the source and load is described. The new circuit exhibits a significantly reduced common-mode noise compared to its counterpart that is implemented with separate source and load grounds. The EMI performance of the proposed implementation was experimentally verified on a 540-W...
On board power supplies for UMTS base station applications are challenging and require special design considerations particularly for low noise output voltages and low EMI interference. This paper gives an insight to the concept called "3rd generation power management". Every base station module has its own galvanic insulated power supply and distribution depending on the type of board....
