Abstract :
A novel nonlinear resonant pole soft switching inverter is used to drive a 4 kW three-phase induction motor in a high-performance drive system. The switching elements are insulated-gate bipolar transistor (IGBT) power modules rated at 25 A, 1000 V. Device voltage stresses are of the order of 1 p.u. The peak current stresses are as low as 1.3 p.u. A sliding-mode stator flux field orientation scheme based on direct self control is chosen as the motor control scheme. The overall control is carried out using a T800 transputer system programmed in OCCAM
