Abstract
PURPOSE: To simplify the configuration as well as to stabilize the function of the device against temperature fluctuation by a method wherein the pulse width modulated wave is created by means of plural pieces of magnetic cores.
CONSTITUTION: The square wave AC voltage is generated from DC by means of the inverter 1, and this voltage is applied to the transformers T1 and T2. The pulse length modulator 2 is connected to the secondary winding of the transformer T1. When the induced voltage of the magnetic cores C1, C3, C5 is taken out and the output transistors Q3, Q5 are driven, then, the pulse length modulated waves are obtained as the output voltage of the transformer T2. This waveform does not include the higher harmonics of the 7th harmonic wave or below, therefore, the higher harmonics of the 9th harmonic wave or above are removed through a simple low level filter in the next stage to obtain the sine wave output.
