Design and implementation of economical cost 30V 1 kW DC-electronic load controlled by microcontroller

Abstract

Electronic load is an importance part of power supplies testing system. For non-electronic load type, it is required to replace a resister with a new one leading to complicated working procedure. The modern power electronic technology is employ to solve this problem. The electronic load can vary the value following user command. Imported electronic load is costly leading Thailand to have a balance of trade deficit. This article proposes design and implement of an economical cost 30V 1 k DC-Electronic Load controlled by Microcontroller. The tested results can confirm the validity of this proposed electronic load
