"A New Modulation Technique to Improve the Power Loss Division Performa" by Md Razon Chowdhury, Md Ashib Rahman et al.
Abstract Multilevel inverters (MLIs) have offered significant contributions toward the implementation of energy conversion units used in industry and renewable energy applications. However, the switching devices in MLIs are associated with power loss division problems. The pulsewidth modulation (PWM) techniques greatly influence the peak, average, and ripple values of the device junction temperature. Thermal tension in the devices may be raised due to increased power loss caused by additional switching or uneven distribution of losses due to unbalanced gate pulses. Higher thermal stress accel...
