efficiency

In a power circuit, the ratio of output power to input power excluding losses. It is represented by the following formula.

(Output Power / Input Power) × 100 (%)

The smaller the losses such as resistance loss that occur when converting input voltage, the higher the efficiency. It is one of the important values indicating the performance of a power circuit, and higher efficiency is more desirable. Since losses ultimately become heat, low efficiency may require heat dissipation measures such as forced cooling. With the recent spread of solar power and storage batteries, power conversion circuits such as power conditioners are becoming more efficient. Toward a future decarbonized society, power conversion circuits are required to be more efficient.
