There are free online resources about industrial and theoretical issues about all aspect of switching power supply design. 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. power electronics engineer need to design power supply day to day. Power supply design is a sophiscated activity involving knowledge in different discipline. This classification is done based on the form of input and output voltage (AC or DC). 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). PFC front end in AC input is found in almost every AC input application. 'Switching mode' is now the dominant type of PSU in almost every spectrum of applications. 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. In both states the power loss or power dissipation is relatively low. This is true because when a switch is on the current is passed with a low voltage while it is off, current is blocked.

Using switches to control energy flow create lower losses and thus SMPS offer higher efficiency when compared with linear power supplies. This kind of power supply are in 'switching mode' and is named as switch mode power supplies (SMPS). Semiconductors which continuously switching on and off are the mostly found key parts to control energy flow of PSU. PSU typically convert AC voltage to regulated DC voltages for electronic equipment. PowerEsim is simulating the power supply in power supply unit (PSU). In this case the device is more accurate to be referred as a 'power converter' than a power supply.Ībout Power Supply Unit, Switching Mode Power Supply (SMPS) and PowerEsim This kind of electronic system converts electric energy to mechanical energy from the source to a given load.
