MOSFET is the most commonly used devices in DC-DC power converters, and its performance is important to the prognosis and health management of power. The paper proposes a degradation analysis model for MOSFET in DC-DC power converters. A method for detecting the degradation of MOSFET is also introduced. Simulations have shown that the method can predict deterioration in the performance of MOSFE...

Abstract A new high efficiency interleaved pulse‐width modulation (HE‐IPWM) method using parallel‐connected Mosfets is presented. The IPWM evaluated a bidirectional DC‐DC converter for charging and discharging battery. results show an excellent DC voltage gain without extremely large duty cycle. Compared with conventional (CPWM), the reduces by half ripple of battery current. current four times...

In this study, the authors propose a non-isolated high step-up interleaved DC/DC converter that can be applied to sustainable energy system. The proposed achieves voltage gain by applying coupled inductor and switched capacitor method based on an boost converter. two inductors connected in parallel with input side have distinct structure. Specifically, single has primary secondary series output...

This paper analyzes one of the most important power capture challenges DC series–parallel collection system, called curtailment losses. The wind speed difference between series-connected turbines causes over- and under-voltage conditions in output voltage MVDC (medium-voltage DC) converters turbine. losses caused by upper-voltage tolerance levels are analyzed considering a redundancy-based limi...

Abstract With the rapid development of China's economy, electricity demand is increasing and scale power grid construction expanding. Large-scale transmission substation projects leads to an shortage corridors, which inevitably formation parallel erection AC DC patterns. When lines are erected in parallel, coupling effect makes hybrid electromagnetic environment more complicated. In this paper,...
