Abstract :
This paper introduces a high-performance switching mode power amplifier with unipolar SPWM for electrodynamic shaker using a simple and efficient voltage-controlled method. And some of control circuitry areas are given. Results of measurements of the output voltage waveform for the frequency band of vibration system with a sinusoidal or random input signal are shown. The presented system achieves THD less than 2% in the required band (2 Hz to 5 kHz).
