Technical FAQs 4

How much power does a pure sine wave inverter use?

Pure Sine Wave Inverter USER MANUAL DC-AC Power Inverter Special Features: Fuse: Built-out 1.5 times rated power for 10s,2 times continue for 2s 120%<Load<150% Rated power for 10s,150%<Load<200% Rated power for 2s Remote Control(Optional) Power ON-OFF switch USB:5V,500mA(Optional) Two multiple controlled DC fans: Temperature and Load.

What is a modified sine wave inverter?

However, the modified sine wave inverter is quite limiting as it does not operate with most of the modern appliances. A pure sine wave inverter has low harmonic distortion and delivers clean power, pretty similar to what you experience from your grid. This makes it ideal for sensitive equipment.

Which MOSFET should I choose for my inverter?

Selection of MOSFETs depends on the power rating of your inverter design. Commonly, IRF3205 is used in most inverters. Push-pull topology is used due to its high power handling capability. We want to step up the DC voltage from 12/24 volts to 311 volts (peak of sine wave voltage).

How to generate square waves with a microcontroller?

If you are generating square waves with a microcontroller, then you have to use a MOSFET driver like IR2210 to drive the push-pull converter MOSFETs. Alternatively, you can also use PWM controller ICs to generate the two square waves. The advantage of using PWM controller ICs is that you don’t have to use a MOSFET driver.
