Inverter-Less Integration of Roof-Top Solar PV with Grid Connected Industrial Drives

Green energy from Solar PV is getting increased attention in the industries due to falling price of solar panels world market. A grid-tied inverter one major components such a system, where DC converted AC and synchronized with grid obtain power sharing between for industrial drives. In this paper, link has been proposed instead an interconnection system run those most modern applications, induction motors are driven by VVVF (Variable Voltage Variable Frequency) inverters achieve efficient speed control. The commonly have rectifier section at front end that rectifies input then used PWM mode generate required voltage frequency motor operating under variable load conditions. Such can use both or as so long supply right value operate. our proposition, we eliminate link, created rectified regular PV, power-sharing output grid. Using directly energize impact on performance inverter. array designed way remains supplementary source only supplement any shortfall sunshine control circuit novel technique inexpensive, efficient, simple design when compared inverters. implemented Niagara Textiles Gazipur, Bangladesh. experimental/practical results presented validate basic concept. Around 20% reduction cost reported more than 90% system. This will definitely make competitive attractive its simplicity.
