| Abstract |
The PV (photovoltaic) system can be used with RL loads on the grid side. However, when RL Load is connected, the phase of the grid current and voltage will not match due to the reactive current component. The reactive current generated at this time can be compensated by the inverter. In the case of such a single-phase PV system, a total of two current sensors are used to detect the inverter output current and the RL load current. This paper proposes a compensation technique using one current sensor without using two current sensors in a single-phase photovoltaic power generation system connected with an RL load. |
