Hi
This is mechatronis project , where Most commercially available low-cost DC-AC converters (Frequency control / inverters) give a square wave of 50Hz output. This is sufficient for a number of devices, especially for devices operating with a transformer. The professional training that a sinusoidal output signal is generated, can also be used to control motors, but is much more expensive. The intention is to build this type of control with the microcontroller. The intention is that through a screen and some buttons speed and run speed is adjustable. Expansion into three phases is not asked at first, but a possible extension.
