Abstract
Provided are a method and apparatus for controlling switches included in an inverter of a power conversion system. A power conversion apparatus of a photovoltaic power generation system includes a processor configured to obtain a first current value at a first terminal of a filter included in an inverter from a single current sensor, obtain a second current value at a second terminal of the filter included in the inverter based on the first current value, and control a switch according to a pulse width modulation (PWM) method based on the first current value and the second current value.
Claims15
A method for controlling a switch included in an inverter of a power conversion system, the method comprising:
- obtaining a first current value at a first terminal of a filter included in the inverter from a single current sensor;
- obtaining a second current value at a second terminal of the filter based on the first current value;
- and
- controlling the switch according to a pulse width modulation (PWM) method based on the first current value and the second current value.
A power conversion apparatus of a photovoltaic power generation system, the power conversion apparatus comprising a processor configured to obtain a first current value at a first terminal of a filter included in an inverter from a single current sensor, obtain a second current value at a second terminal of the filter included in the inverter based on the first current value, and control a switch according to a pulse width modulation (PWM) method based on the first current value and the second current value.
