How to choose a good inverter power devices

Select essential elements of the inverter main power is currently using more power components Darlington power transistor (GTR), power FET (4000 watt power inverter), insulated gate transistor (IGBT) and a turn-off thyristor (GTO) and the like. Used in small volume, low pressure systems more devices to MOSFET, because the MOSFET has a low on-state voltage drop and higher switching frequencies; capacity in the high-pressure system in general IGBT modules are used, this is because as the voltage MOSFET 5000 watt inverter its on-state resistance also increased, while the IGBT has a large advantage in the capacity of the system; while large capacity (100KVA and above) systems, in general, are used GTO as power components.

Inverter role ?

Is the DC power ( battery , storage battery ) into alternating current ( typically 220v50HZ sine or square wave ) . Popular speaking , the 4000 watt power inverter is a direct current (DC) into alternating current (AC) devices. It consists of inverter bridge , and filter control logic circuit .Widely used in air conditioners, home theater, electric wheel, power tools , sewing machines , DVD, VCD, computers, televisions, washing machines , range hoods , refrigerators , VCRs, massage , fans, lighting and so on.Briefly, the inverter is a low voltage ( 12 or 24 volts or 48 volts ) power to an electronic device 220 volts alternating current. Because we usually rectified to 220 volt inverter olts AC into DC to use, and the role of the inverter on the contrary, hence the name. We are in a "mobile " era , mobile office, mobile communications, mobile leisure and entertainment. In moving state , people not only need low voltage direct current from a battery or battery supply , but we need more indispensable in our daily environment 220 volts AC inverter to meet us this demand.
