Abstract
The development of digital devices has led to the production of PWM inverters for driving induction motors having high-frequency carriers over 10 000 Hz. However, the popular digital devices exhibit difficulties in arriving at the precise switching instants because of limitation of available memory capacity and of bits, especially in the low-frequency region. Basic discussions on the magnetic flux and torque ripple and an introduction to a memory-saving and low-torque-ripple new PWM (split zero vector) method are given. The experiments show fairly good current waveforms, low iron loss, and low acoustic noise.Keywords
