What is Loss analysis? TopClick here to try Online Loss analysis tool now

Loss analysis may be the most useful tool of PowerEsim. It sort the losses of each component user added or automatically loaded from converter, and give a break down on what kind of losses they are. User can improve efficiency or cost by just choosing different component from different manufacturer.

Most crucial parameter - Total Loss TopClick here to try Online Loss analysis tool now

User can change operating condition, e.g. input voltage, output current, and component and press "Recalculate" for new losses.

Individual Component Loss shown TopClick here to try Online Loss analysis tool now

A break down of losses is given for some component. User can have more information on how the losses of individual component come from.

Conduction Loss TopClick here to try Online Loss analysis tool now

For example, conduction losses of a diode means forward drop losses.

Switching Loss TopClick here to try Online Loss analysis tool now

Switching losses of a diode means the sum of reverse recovery losses and reverse leakage current losses.

Fringing & Leakage Flux Loss TopClick here to try Online Loss analysis tool now

Losses of a magnetic component divided into three part, core losses means the total ac losses including the hystersis and eddy current losses. "Conduction losses" means the dc copper losses. Fringing & leakage flux losses means the sum of all ac losses in the copper, e.g. ac losses caused by skin and proximity effect, eddy current losses caused by fringing flux, etc.
