Stand-alone PV systems are increasingly being used in rural areas to drive basic loads typically less than 300 VA. Such systems are beneficial where grid electricity is unreliable or not present at all. A 250 VA battery integrated stand-alone PV system is proposed here. This PV system is based on simple hardware structure. It is possible to design this system at lower cost with higher reliability...
The common mode (CM) voltage and current issues due to the parasitic ground capacitance have been well reported for the PWM converters. However, most of the previous work focused on the CM voltage generated at the motor side, or the input/output filter design for the standard compliance purpose. This paper identified a unique ground loop resonance phenomenon for the cascaded H-bridge multilevel inverter,...
In this paper, the design guideline for a high-power-density inverter for fuel-cell applications is presented. Such an inverter can lead to savings in volume and weight due to high-frequency operation. Also, we present a guideline to determine the optimal size of the input filter. It is also illustrated that, for such a topology, an optimal choice of transformer leakage inductance is necessary to...
