Title: Sinusoidal wave pwm inverter
Inventor: SHIBUYA TADASHI
IPC: H02M7/48
Filed: 1985-12-27
Abstract: PURPOSE:To eliminate a DC component to be generated due to a dead time by detecting the DC component from the output current of an inverter, and adding this detection signal as one bias in a direction that the DC component becomes zero in comparison with a sinusoidal wave with a carrier. CONSTITUTION:A current transformer 13 for detecting the output current of an inverter 1 and a low pass filter 14 for removing an AC component from the detection output of the transformer 13 are provided. A DC bias is applied to the output of a sinusoidal wave generator 4 by the output of the filter 14. The sinusoidal wave is biased by the transformer 13 and the filter 14 for the superposition of the DC component on the output current of an inverter due to the variations in the power factor of a load 3 and in the offset voltage in the comparison of carrier wave with the sinusoidal wave, and applied in the polarity for cancelling the bias by the superposition of the DC component. Thus, the DC component is eliminated from the output of the inverter 1 to prevent the output transformer 2 from being heated.
