Loads are classified into resistive loads, inductive loads, and capacitive loads according to their impedance properties. Resistive load: A load with no phase difference between current and voltage is a resistive load, such as rice cookers, light bulbs, electric stoves, electric soldering irons, etc. Inductive load: The load when the current lags the voltage by a phase difference is an inductive l...

The power factor of the photovoltaic grid-connected inverter is a point that has to be mentioned in the technical parameters. In an AC circuit, the cosine of the phase difference (Φ) between the voltage and the current is called the power factor, which is represented by the symbol cosΦ. In terms of value, the power The factor is the ratio of active power to apparent power, that is, cosΦ=P/S. Gener...
