What is Power Supply/Power converter?
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.
About Power Supply Unit, Switching Mode Power Supply (SMPS) and PowerEsim
PowerEsim is simulating the power supply in power supply unit (PSU). PSU typically convert AC voltage to regulated DC voltages for electronic equipment. Semiconductors which continuously switching on and off are the mostly found key parts to control energy flow of PSU. This kind of power supply are in "switching mode" and is named as switch mode power supplies (SMPS). Using switches to control energy flow create lower losses and thus SMPS offer higher efficiency when compared with linear power supplies. This is true because when a switch is on the current is passed with a low voltage while it is off, current is blocked. In both states the power loss or power dissipation is relatively low. SMPS have smaller number of passive components and lower heat generation (due to less power loss), thus SMPS can be smaller in size and is lighter in weight in general. "Switching mode" is now the dominant type of PSU in almost every spectrum of applications. PFC front end in AC input is found in almost every AC input application.
There are four types of SMPS: AC to DC (AKA: off-line DC power supply); DC to DC (AKA: voltage or current converter), AC to AC (AKA: frequency changer or cycloconverter), and DC to AC (AKA: inverter). This classification is done based on the form of input and output voltage (AC or DC).
Power supply design 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 switching power supply design.
It also includes many smps and power electronics circuit, schematics, topologies, theory of operation, application note, circuit analysis, on line educational course material.
