The inverter is built to withstand a wide range of harsh environmental conditions. It is highly resistant to dust, humidity and temperature extremes, making it ideal for outdoor installations in areas with varying weather patterns. This makes it particularly suitable for agricultural, industrial and rural water pumping applications where the ability to rely on an uninterrupted water supply is critical.#7.5kw pump inverter three phase

In the control system, through the simulation method, the SVPWM and SPWM modulation methods are analyzed, and the SVPWM control method with low switching loss and higher DC bus voltage utilization is selected, which makes the utilization rate of DC voltage 15% higher. Then, the auxiliary circuits in the system are designed and parameters are selected. Finally, the overall system was debugged and parameter tested, including: dead time test, configured dead time 2.67μs, dead time occupies 10% of the entire PWM cycle to ensure that the software runs normally; FFT test analysis after filtering After 50Hz～60Hz, the harmonic content is very small, the basic attenuation is zero, and the filtering effect is achieved.
