Application of half bridge topology for ultrasonic transducer excitation using long pulse trains is presented. The novelty of the approach is the high speed solution for a high side drive. A commercially available high speed digital isolator and a high speed MOSFET driver were combined to give the possibility to deliver fast driving signals to a high side N-channel MOSFET. The experimental investigation indicates that the output amplitude of the fundamental harmonic can reach 624 Vp-p for light… CONTINUE READING
