Resonant Tank Motor Model For Voltage Reflection Simulations With PWM Drives

Reflected wave transient voltages that are impressed on drive output cables and low voltage AC induction motors are normally simulated with steep fronted dv/dt pulse waveforms from PWM voltage source inverters. System simulation arises from a need to correlate reflected wave peak voltage and risetime with the dielectric insulation capability of both the motor and cable. To obtain reasonable results, accurate models of each component must be employed. This investigation concentrates on parameter identification for a high frequency resonant tank motor model from fractional to several hundred horsepower
