Reliability of the grid feeding or stand-alone inverter system is a concern. Apart from the power electronic switching devices, DC link capacitors have an impact on reliability of the whole system. Two different PWM switching schemes are analysed for a 3-level DC-DC converter connected to a single phase NPC inverter. To reduce the current stress on DC link capacitors, it is suggested to use inverter...
MTBF Mean Time Between Failure is a life unit as a million hours or years of the electronic product or systems. Reliability engineering as a scientific discipline is introduced in this paper, with an emphasis on the specific nature of reliability analysis. Applications of reliability analysis in the form of reliability tests are discussed for the ZCZVT (Zero Current Zero Voltage Transition) PWM (Pulse...
A novel dual-boost half-bridge (DBHB) reversible pulse width modulation (PWM) rectifier is proposed in this paper. Compared with the conventional full-bridge or half-bridge reversible PWM rectifier, the proposed DBHB rectifier exhibits two distinct advantages: (a) No power switches are connected in series directly in one leg, and the operation reliability is greatly improved for its inherent immunity...
