A simplified inverter model for online control and simulation

A simplified fundamental component model for sine triangle comparison pulse width modulated (PWM) inverters operating in the transition region is presented. The model is evaluated by comparing it to detailed inverter simulations and through experimental verification. Results from a real-time control application show that the model compensates for the reduced inverter gain due to bus voltage variation and operation in the pulse dropping region. Application of the model to high-performance drives is explored.<
