| PowerEsim Help Manual |
| PowerEsim is a free web-based software providing power supply (SMPS) design, transformer design, magnetic design, loss analysis, thermal analysis, waveform analysis, MTBF analysis, BOM building, DVT analysis and optimization of power supply (SMPS). | |
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.
User can
change operating condition, e.g. input voltage, output current, and component
and press “Recalculate” for new losses.
A breakdown
of losses is given for some component. User can have more information on how
the losses of individual component come from.
For
example, conduction losses of a diode means forward drop losses.
Switching
losses of a diode means the sum of reverse recovery losses and reverse leakage
current losses.
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.
