Design for Reliability of Power Electronics for Grid-Connected Photovoltaic Systems

Abstract: Abstract-Power electronics is the enabling technology for optimizing energy harvesting from renewable systems like Photovoltaic (PV) and wind power systems, and also for interfacing grid-friendly energy systems. Advancements in the power semiconductor technology (e.g., wide band-gap devices) have pushed the conversion efficiency of power electronics to above 98%, where however the reliability of power electronics is becoming of high concern. Therefore, it is important to design for reliable power electronic sy… Show more

“…The increased number of semiconductor devices increases the risk of failure since the failure of a single device could cause the whole inverter to fail. Researchers have studied the reliability of power electronics to a great extent in an attempt to reduce the risk of failure and to increase the reliability of power electronic systems for distributed energy resources [6], [7]. The most common faults that may occur in MLIs are open and short circuit faults in power switches [8].…”

“…It is possible to determine the operating voltage of the motor, recalling (10): (10) If the threshold of (5) is exceeded, the MTPA trajectory cannot be used any longer, and the control point should be determined by the flux-weakening technique intersecting the current circle with the voltage ellipsis in the dq plane (CPSR operating region). This gives the polynomial (11), again with order four: (11) In this case the desired solution is the maximum among the negative (and real) ones. If all those constraints lead to unacceptable solutions, it means that the requested operating point is unachievable by the motor.…”
