Abstract

Small scale hydroelectric projects are gaining popularity worldwide. Installation of mechanical controls to consistently produce quality power generated can be expensive.One cost-effective solution is to use Electric Load Controllers (ELC) using component that are commercially available in the local market. The voltage, current and frequency of a 200W synchronous generator were measured at varying speed and load intervals to define the parameters to consider in the design of the ELC. Using Pulse Width Modulation scheme , the design was guided through computer based simulation using components database and actual testing of various blocks using locally acquired components, Components selection was only based on the suitability to the design but more importantly the availability to the local market and common consumers. The block prototypes were able to produce the desired response signal of the ELC in each process high sample voltage indicated effective switching of the dump load. As a whole circuit the virtual simulation showed that the ELC was able to steer power accordingly to desired response the duty cycle. The integrated block circuits, however, showed a need for improvement on the isolation and switching circuitry.
