Pure Sine Wave Power Inverter 3000W
Pure Sine Wave Power Inverter 3000W
This project showcases our custom-built pure sine wave power inverter using SPWM (Sinusoidal Pulse Width Modulation) with the EG8010 controller. The inverter converts 48V DC to 220V AC, delivering 3000 watts of output power.

Description
We are using SPWM EG8010 as driver board that can be ordered from here:
Transformers information:
- T1 and T6 are current transformers 50Hz/3kW like this one here: Current Transformers
- T2 is the big toroid with params A-B 32V 80A, C-D 220V 15A
- T3, T4 and T5 are filtering toroids for 23kHz
More info is coming soon…
Parts
- STW52NK25Z – can be replaced with any other N Channel MOSFET that have at least 200V for drain source voltage:
