Abstract

PURPOSE:To enable matching of the reference levels of the output wave-forms of a sine wave and a triangular wave easily by connecting two power supplies to a triangular wave generating circuit, using the neutral point as the reference level and passing the output of a sine wave generating circuit through a capacitor. CONSTITUTION:A variable power supply 5 controlled by the signals of a temperature, etc. is connected to the positive side and negative side of the sine wave generating circuit 1, and the output of the sine wave is supplied to a modulation circuit 3 through the capacitor 6. On the other hand, two power supplies 7, 8 are connected in series at the positive side and negative side of the triangular wave generating circuit 2, the neutral point is used as the reference level, and the output of the circuit 2 is fed to the modulation circuit 3. Accordingly, since the output wave-form of the sine wave is oscillated in the positive and negative directions by passing it through the capacitor 6, the output wave-form of the triangular wave is amplified between the positive side of the power supply 7 and the negative side of the power supply 8 and the optimum wave-form can be obtained as the input signals of the modulation circuit 3, signals for generating the three- phase AC output wave-form of an inverter can easily be acquired.
