A "220V to 110V voltage converter" is an electronic device designed to reduce 220 volts to 110 volts. It does this by cutting off half of the peak-to-peak sine wave. Very simple. Thus, the electricity varies from zero to max volts and back to zero. It does not go to negative volts. It stays at zero volts for half of the sine wave. Therefore, what comes out of a converter is on-off power, at a frequency of 50 Hz
