PowerEsim is a free web-based power supply design tool which is sponsored by component manufacturers and active members. It provides a virtual environment that users can build hundreds of "real" power supply with real constructed transformer and see all loss, stress, life, temperature in a fraction of a second.
The circuit simulator is a combination of iteration, equation based approach and time step integration. The circuit is defined by non-linear equations and the simulator will first solving the switching condition solution for t=infinity by bracketed iteration, then fine step of point by point results will be generated by those equations for V, I and loss analysis.
More than 30 topologies are available including Flyback converter, Boost converter, Buck Converter, Buck-Boost converter, Half-Bridge converter, Full-Bridge converter, ZVS Phase Shift Full-Bridge converter, ZVS active clamp converter, ZVS asymmetric converter, PFC CCM converter, PFC DCM converter, two wheeler/switches forward converter, Interleaved two wheeler/switches converter, RCC Flyback converter, LLC converter, Emitter Driven Flyback converter, Sync-buck converter and Ballast converter.
Magnetic Builder is part of the powerful design tool that allows users to create magnetic components by selecting different core materials, bobbin type and winding methods. All the custom magnetic components can be saved and incorporated onto a power supply. Engineering drawings will be automatically produced to reduce user work load.
