Current or Time Sharing Switches for High Efficiency Photovoltaic Power Systems

Abstract: This paper presents a comparative analysis of the parallel operation of different switches in a switch mode power converter. In high power applications, multi-switch PWM power conditioners may be preferred despite a higher component count, due to the absence of low frequency filters, reduced switching losses and fault tolerance. The paper demonstrates how current sharing (CSH) and time sharing (TSH) lead to the reduction of switching stress in the parallel operation of switches in any converter. The solutions … Show more

“…In order to improve the paralleling performance, Parick Hofer presents an active gate-controlled current balancing method to balance the static and dynamic behavior and then the temperature [12]. H. Dehbonei suggests that when IGBTs are applied in parallel, TSH (time sharing) should be used to reduce the stress on the switches while guaranteeing maximum performance in a system [13].…”

“…Los resultados obtenidos muestran un mejor comportamiento de los MOSFET cuando circula corriente simultáneamente a través de dos transistores. En el caso de los IGBT los resultados son mejores cuando se aplican métodos de reparto del tiempo de conducción [DEH06].…”
