摘要：
Subject of this contribution is a novel PWM controlled inverter of the kW power range, feeding a multi-mass ultrasonic motor (MM-USM) via a LLCC-type filter. The system is designed in a way to reduce the total harmonic distortion of the motor voltage and to locally compensate for the reactive power of the motor. Operating a three-level inverter with PWM pattern of eliminated low-order harmonics allows the use of a small and lightweight output filter showing besides impoved dynamic behavior.
