What is Power Supply/Power converter?

Supply of power electrical power is called a power supply. Electric energy is transformed to be the engine of any power supply. This kind of electronic system converts electric energy to mechanical energy from the source to a given load. In this case the device is more accurate to be referred as a "power converter" than a power supply.

What is design of Power Supply?

Design of Power supply is a sophiscated activity involving knowledge in different discipline. power electronics engineer need to design power supply day to day. To support and simplify their job, PowerEsim is here to be used as a virtual lab or virtual branch so that steps in SMPS design: the selection of component; building of transformer; thermal simulation; power loss estimation; waveform chart recording; failure rate calculation; PPM estimation are done in one click. There are free online resources about industrial and theoretical issues about all aspect of design of switching power supply. It also includes many smps and power electronics circuit, schematics, topologies, theory of operation, application note, circuit analysis, on line educational course material.

What is Transformer?

A transformer is a device that transfers electrical energy through it's coils (an inductively coupled conductors). Varying current through the first or primary winding creates a varying magnetic flux in the transformer's core, and thus a varying magnetic field in the secondary winding, induces a varying electromotive force (EMF) or "voltage" in the secondary winding. This effect is called mutual induction.

What is Transformer Design? How to do Transformer Design?

Transformer design is a complex activity to construct a up-to-standard transformer. This including selecting different ferrite core, bobbin type, number of winding, winding method, etc. The designing process is targeting for a smaller, lower power loss, lower temperature and stable power output. Tranditional transformer design process include tedious replace and try process to find a suitable combination of core, wire and type. Thus the efficiency of transformer designing process depends on the experience of engineer. PowerEsim provide virtual branch to perform testing on combinations of different core and wire of different manufacturer. This speedy platform allow user to get result of each combination of transformer in seconds.
