Three-phase grid-tied photovoltaic inverter with reactive power compensation capability

Abstract

In this moment, different alternatives exist to generate electric power across the natural resources use. One of the most popular options is making use of solar energy by photovoltaic (PV) cells and power electronic converters. Both elements constitute the photovoltaic systems (SFV). Although today, you can find a number of different topologies of converters, it is necessary to look for alternatives that offer all the possible advantages in order to achieve a better use of the solar resources. This paper proposes the construction of a prototype which topology is already known as 3 phase full-bridge inverter (30) to perform not only injection of active power (P), but also have the capability to inject and/or absorb reactive power (Q), by means of a suitable control scheme.
