Frequency sinus source

In the paper are presents the results of a practically realized on variable frequency sinus source. This source generated sinusoidal voltage with amplitude from 0 to 220 V and frequency from 0 to 100 Hz. The solution is based on EG8010 integrated circuit and driver circuit IR2010s. Control electronics operate IGBT transistors in the topology of full bridge. The operation of the circuit is verified with oscillograms and data obtained from measurements of the practically realized prototype
