Loss analysis may as well be the most useful tool of PowerEsim. It sorts the losses of each user added or automatically loaded component from the converter, and gives a breakdown on the type of losses they are. Users can improve efficiency or cost just by choosing different components from different manufacturers.
5.2 How to start Loss Analysis as a Standalone ToolBack to top
Click on "Loss " on the left main menu to start Loss Analysis.
5.3 Introduction to Interface (Standalone Tool)Back to top
The user must first add at least one part into the design. To add parts into the design, click [+Part] in the top bar. For details, please refer to Session 14--Add Parts.
There are shortcuts to start a design from choosing topology before using this tool. To start a design using another method, please refer to Session 2.2--Start a power supply design.
All components in the design are automatically loaded to this tool and shown in the component list.
Individual component loss of each components are shown including conduction loss, switching loss and fringing & leakage flux loss.
Conduction losses mean forward drop losses.
Switching losses mean the sum of reverse recovery losses and reverse leakage current losses.
Losses of a magnetic component divided into three parts:
"Core losses" mean the total AC losses including the hystersis and eddy current losses.
"Conduction losses" mean the DC copper losses.
"Fringing & leakage flux losses" mean the sum of all AC losses in the copper such as AC losses caused by skin and proximity effect, eddy current losses caused by fringing flux, and so on.
