The efficiency of a system in electronics and electrical engineering is defined as useful power output divided by the total electrical power consumed (a fractional expression ), typically denoted by the Greek small letter eta (η – ήτα). If energy output and input are expressed in the same units, efficiency is a dimensionless number.
The biggest motivation and driver for semiconductor power device innovation is improved efficiency in power conversion. Power gallium nitride (GaN) technology shows the greatest performance benefits against other incumbent technologies, including silicon (Si) technology. A reduction in power losses is the key challenge
Power supply efficiency ratings are this ratio in percentage form. For instance, let''s say a device needs 360W to run. Its power supply takes 450W from the socket, converts it to DC with some expected loss, and gives the device the 360W it needs. This power supply would have a rating of 80% (360/450).
