Power Electronics Simulation Software
Therefore this technique can't entirely substitute breadboarding and prototyping. On the other hand, it allows measurements of internal currents, voltages and power, that in many cases are virtually impossible to do any other way.
Most general-purpose programs are based on various versions of SPICE (Simulation Program with Integrated Circuits Emphasis). They can handle analog, logic and mixed-signal components. In SPICE, circuits are presented by so-called netlists. The program initially 'guesses' all node voltages and calculates all the currents. These currents are then used to recalculate the voltages. Such iterations continue until all the values stabilize. Failure to settle after a pre-determined number of iteration creates so-called no convergence error.

Therefore, to get proper results in non-linear circuits you need to learn the modeling and solve convergence problems. Large companies usually buy commercial software, such as PSpice®. It is integrated with OrCad and includes schematic capture, extensive model libraries, and waveform display and analysis functions. A schematic capture allows you to draw the circuit diagrams and automatically translate them into netlists.

Some packages also provide circuit design and even PCB layout. Unfortunately, commercial electrical design and analysis packages are relatively expensive for an individual. Designers who want to simulate their circuits without buying a full package have several options: 1) Working demos (usually limited to small-size circuits with many functions disabled); 2) Open source programs (with little or no tech support); 3) Software provided by the component manufacturers (often good only for the designs that use these manufacturers' parts); 4) Online tools provided by enthusiasts. Among free programs the most popular is LTspice provided by Linear Technologies. This is probably the only complete SPICE freeware, although PWM controllers and most other parts in its library are from Linear itself. Well, of course, since it is free, why would they provide third party models? There are also programs that let you not only simulate but actually design too.
PowerEsim helps you choose a topology and calculate its main parts as well as magnetics and it's completely free. Ridley's POWER 4-5-6 provides component design with feedback loop and large-signal simulation, but his free demo is quite limited.
I am personally using its paid version. Here you will find best free electronic circuit simulators, power supply calculators, and other electrical engineering design tools available on the web.
