Abstract :

 A transformer performs many functions such as voltage transformation, isolation, and noise decoupling, and it is an indispensable component in electric power distribution systems. However, at low frequencies, it is a bulky and expensive component. A fairly straight forward approach to accomplish size reduction in a transformer feeding a conventional rectifier, inverter, UPS, etc system is to introduce a high frequency transformer. Such ac–ac converters need switches with bi–directional voltage blocking and current carrying capability, which are commonly realized with pairs of gate turn–off devices such as MOSFET.This paper reports on generation of gate pulse for H–idge on both side for electronic transformer and explain the advantage of symmetric modulation scheme over asymmetric modulation scheme.
