Abstract

Today, using the conventional technique to obtain the fast transient load response for the forward converter is not easy. Therefore, in order to overcome this problem, a forward converter with a complex programmable logic device (CPLD) technique added is presented herein along with a hysteresis voltage-controlled pulse width modulation (PWM) scheme and the maximum current limiting, without any analogue-to-digital converters (ADCs). Also, some protection functions are added to enhance the reliability of the proposed topology, thereby allowing this converter to be likely to approach to industrial products. The validity of the proposed topology is demonstrated via some experimental results compared with those created from the conventional topology.
