energy saving wind turbine micro inverters for sale with Anti-Islanding Protect

Application:

SWI Series Adopt precise vector wind speed automatic control function. In different wind speeds, the output voltage of wind power generator is different. It means the output voltage is not stable in the long run. It's very hard to control working condition in the steady state whether for the battery control or inverter system. Because of the unsteady voltage of the wind turbine, the inverter using load for automatic control wind power generator speed, at high speed, load increasing, at low speed, load corresponding reducing. It could make the wind power generator in a constant speed state and control the output voltage at stability of wind power generator. In the same time it could make the wind generator power of all the output to the load! Then greatly improve the efficiency of wind power and its utilization rate of increase! The experiment shows that this system could make the utilization rate of wind power up by more than 40%. And do not need to connect battery.

System Function :

1.AC 0 angle with high precision auto-detection

AC phase angle of 0 through isolation amplifier then input to the MCU for high-precision detection and analysis. The phase shift rate is less than 1%, thus achieve high-precision with phase modulation AC output together.

AC phase shift: < 1%
Over-zero protection: 0.2 VAC
AC switching: 50Hz / 60Hz

2. Synchronous High-frequency Modulation

In the process of the grid, usually adapt the same phase angle in parallel. (ie, When the two-phase alternating current total is equal to 0.Use switch to combination the two AC fusion) and the product is rectified AC half-frequency AC to 100Hz first, then the machine use the high frequency current in the circuit and semi-100Hz frequency alternating current generated combination, to achieve high-frequency modulation.

1) Modulation synthesis: half wave and full-bridge modulation synthesis (100Hz / 120Hz)

2) Synthetic way: MOSFET full-bridge

3) High frequency: 50KHz

3.Pure Sine Wave Output

Use SPWM directly to make pure sine wave outpu

1) Output waveform: Adopt complementary PWM to push-pull pure sine wave.

2) Generate means: enhancement-mode SPWM

4.Automatically Adapt To Different Load Power Factor

Adapt to any of the power load
