Abstract :
The development of pulse-width-modulation (PWM) power amplifiers based on fast-switching MOSFETs and their applications are described. Their ability to drive magnets efficiently, neutralize power line harmonics, and control motion with precision is examined. Active filter and active magnetic bearing implementations are discussed.<>
