Abstract: Abstract—Analysis of the dynamic sharing currents at turn-on process in power PWM inverter system with switching Metal-Oxide-Semiconductor-Field-Effect-Transistors (MOSFET's) connected in parallel is presented. The inverter circuit presented in this paper is low power inverter which can be used as a charger too. The influence of the diferent rise time driving signals and parameters mismatch between parallel MOSFET branches, over wide operating ranges is analyzed, resulting in dynamic currents, transition energy unbalance, time delay on switching process of parallel MOSFET's, and time delay at output voltage of inverter. One of many potential causes of mismatch parameters is the threshold voltage Vth. Results are presented for the time delays during On switching of the parallel branches in inverter with five power MOSFET's in each of two legs, selecting same threshold voltage initially, for various rise time driving signals of the two legs of inverter when only one !
MOSFET in particular leg has lower threshold voltage than others.
Keywords: Dynamic current, Mismatch parameters, PWM- Pulse Width Modulation, Rise time, Switching, Threshold voltage, Time delay.
