3KW inverter IGBT bridge driver

recently done a 2000W after class , the number of W-3000W SPWM after class can easily be changed , can be a convenient output pure sine wave form control board with two plans , the effects are as follows < / p > 1, the main control board practical unipolar with bipolar SPWM output , just change the number of resistors can be achieved with the substrate to distinguish .

2, DC input 0-400VDC.

3, the output voltage can swap board potentiometer .

4,Grid tie inverter, by the board potentiometer to achieve the largest areas of regulating the output frequency 0 - 400Hz .

5, the board can choose welding Hall electrical propagation sensor for high-precision current detection .

the board power tube temperature detection sheltering .

7, onboard fan initiative dominated interface, can take the initiative to moderation fan start and stop .

8, perfect maintenance of a short circuit , the output can be any short circuit , automatic recovery after the abolition of short-circuit ,www.12vgridtiepowerinverters.com, cold , hot start can be driven by any load , currently only test the lamp load , cold resistance approximate short circuit ,power inverter. Bipolar mode , sudden 2KW bulb , voltage recovery time in 400ms .
