In this paper, the ripple current of a 3 kW solar inverter for residential use is measured. In order to prove the existence of a power loss due to the second harmonic ripple current the output power of the solar cell module is measured in the presence of the second harmonic current in the output.

High current ripples affect the dynamic response of the PV panels and make it difficult to maintain the system to operate at maximum power point. Using an interleaved boost converter (IBC) and driving the converters in critical conduction mode (CRM) is a well-known solution for reducing high current ripple and switching losses in power supplies.

Experimental results indicate that the output voltage lags to some degree as the output current is higher than that at the maximum power point (MPP), leading to deterioration in the output power. This problem can be alleviated by adding a filter capacitor at the output of the solar-cell panel or increasing the operating frequency of the power .
