Microcontroller Based Advanced Triggering Circuit for Converters/Inverters
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 1
Abstract
This paper presents an advanced method of generating triggering pulse using Microcontroller (8051) whose delay angle is controlled by the feedback signal given by Analog to Digital Converter (ADC) to Microcontroller (8051). The use of microcontroller based control circuit provides us large number of advantages. It reduces size and cost of controller significantly. The efficient control of delay angle is the main advantage. Besides this it provide more versality and greater scope for further improvement just by changing the program but not hardware configuration. Its long life and no fatigue are the most appreciated characteristics. The generated triggering pulse is synchronised with supply frequency and recorded for various delay angle. Zero Crossing detector (ZCD) is used to detect the zero crossing of the supply. The performance of controller is found satisfactory. In general switching control mode as well as specific application mode.
