Three Phase Inverter
A three phase inverter is a device that converts dc source into three phase ac output . This conversion is achieved through a power semiconductor switching topology. in this topology , gate signals are applied at 60-degree intervals to the power switches , creating the required 3-phase AC signal. This type of inverter commonly employed in conjunction with photovoltaic(PV) modules or the grid . The fundamental principle behind its operation involves the use of three individual inverter switches , with each switch is dedicated to one of the three output phases. To generate a balanced and synchronized ac output waveform , these switches are precisely controlled. Each switch operates at specific intervals , ensuring that only one switch is active at every 60-degrees of the basic output waveform . In essence , a 3-phase inverter is a crucial component for efficiently converting DC power into 3-phase AC power needed for various applications, especially in renewable energy systems like solar PV installations and industrial setups where three phase power is essential for running machinery and equipment.
