Precision Simulation of PWM Controllers
Modeling of Voltage Sourced Converters (VSC) with Pulse Width Modulation (PWM) is possible using large simulation time steps. This paper introduces the latest simulation algorithm used in the EMTDC program (called the Instantaneous Solution) and makes comparisons against small time step solutions (to show the effectiveness of Interpolation).
