Use of ASICs in PWM techniques for power converters

Abstract

The authors present a PWM ASIC that is part of a general driving-and-control board of an induction machine. Like the other ASICs, the PWM ASIC has to perform efficiently a specific-and thus simple-job. It is part of a full digital board design. So a PWM solution is presented that is easily implemented inside a digital ASIC. Some results show that a good performance is obtained with this low-cost and easy-design IC.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
