Pure Sine Wave Inverter/300W Pure Sine Wave Inverter dc12V ac 220V 50hz
The 300W pure sine wave inverter are ultimate choice of appliances demand a clean, pure source of AC power.This inverter is a high conversion efficiency model and continuous working module generating a sinusoi-dal wave from a 12V - battery bank, which can supply energy to various loads such as resis-tive load (heater),inductive load (air conditioners, refrigerator),motors (vacuum cleaners), and rectifier load (computer).
1.Low voltage input model adopt original imported IR MOS tube.The current is 5.5 times of rated current.
2.It low voltage input connection adopt high frequency low resistivity electrolytic capacitor. How- ever ordinary capacitor will explode if the temperature become very high.
3.Every transformer has independent fuse protection.If there is a MOS tube break down,then the fuse will break fast.So that will not effect other MOS tube to break.
4.All the protection signal adopt monolithic processing.Circuit is simple and stable.
5.Input and output are isolated to ensure the operation stability
6.Output circuit adopt convertible circuit.The SPWM signal produced by Single Chip Micro computer drive the A3120 optical coupler.Then the optical coupler isolated drive the output through IGBT tube.Adopt negative pressure to cut off IGBT to eliminate Miller effect,so the output is more steady.
7.The whole design adopt patch technology.The circuit is simple and steady.
8.Smart protection function with LED and alarm show.
Designed for a variety of applications such as residential, commercial, emergency and vehicles, construction and solar system etc.
