Supply Voltage Optimisation Using Power Electronic Devices And Pic Microcontroller

 A new voltage optimiser purely based on Power electronic devices was proposed to ensure the voltage on a site maintained at the optimal level. The system was designed in such a way that the voltage supplied to the load was reduced and brought in line with the actual needs of the equipment on the site. Controlling the voltage was one of the simplest and cost-effective ways to reduce electricity use, resulting in electricity cost savings and reduction in carbon emissions, with the additional benefit of equipment protection. In this project, an uncontrolled diode bridge rectifier and controlled bridge inverter formed by MOSFETs were used. The Inverter is an electrical power converter, which converts the direct current to alternating current. ‘The converted AC can be at any required voltage and frequency with the use of Power Electronic Switches,’ by using this principle the project goal was achieved. The Professional ISIS and ARES were employed for simulation studies and practical design of the proposed project. The Inverter was controlled by means of a PIC microcontroller which was programmed using ‘PIC C’ and was able to meet the requirements of controlling the output AC voltage by switching the MOSFETs of the Inverter circuit.
