Junction Temperature Balancing Strategy of Model Predictive Control for Single-phase PWM Rectifiers With Periodic Switching Sequence Alternation
摘要
Abstract
A junction temperature balancing strategy of model predictive control with periodic switching sequence alternation is proposed for single-phase two-level pulse width modulation(PWM)rectifiers.Firstly,the basic principle and implementation of model predictive control method are introduced.Secondly,the mathematical model of fundamental power loss and junction temperature for switching devices is modeled to quantitatively analyze the junction temperature distribution characteristic of the two conventional switching sequences.On this basis,the principle of the proposed periodic switching sequence alternation strategy is presented.The proposed strategy adopts the fundamental period as the alternation cycle,and these two conventional switching sequences alternate,which can achieve the balancing of the steady-state junction temperature of each IGBT and diode over one fundamental period.Finally,the proposed strategy is verified by computer simulations and experimental tests.关键词
