    Analysis Of Grid-Connected Photovoltaic Systems

    Conventionally, grid connected photovoltaic energy conversion systems are composed of a DC-DC converter and an inverter. The DC-DC converter is controlled to track the maximum power point of the photovoltaic array and the inverter is controlled to produce current in such a way that the system current has low Total Harmonic Distortion (THD) and it is in phase with the utility voltage. The efficiency of the conventional system is low because the DC-DC converter and the inverter are connected in series. The purpose of this article is to design a photovoltaic generation system for connection in a three-phase system using only a DC/AC inverter...

    Capacitors - Get More Power & Save Money

    Power factor is the ratio between the KW and the KVA drawn by an electrical load. Where the KW is real power to load and KVA is the apparent load power. It is the measurement how an electrical equipment getting current in actual. A load with power factor of 0.85, results much higher losses in supply system and consumer has to pay higher bill…
