摘要： A control apparatus and a semiconductor apparatus of AC motors capable of reducing torque ripple with a comparatively simple circuit corresponding to a high withstand voltage and capable of driving a motor at high efficiency even when the rotational speed or load has changed. The control apparatus detects first phase signals fixed in relative phase to induced voltages of the motor and current polarity signals, recognizes phase differences between them, generates second phase signals so as to make the phase differences approach zero to drive the motor at high efficiency, generates modulation wave signals having quasi-sinusoidal waveforms or trapezoidal waveforms on the basis of the second phase signals, compares the modulation wave signals with a carrier wave signal, and conducts PWM control on an inverter.

A tilt angle (α) of the inclined plane satisfies: 45°−[arc sin(sin θ/n)]/2≦α≦45°+[arc sin(sin θ/n)]/2, wherein θ is an angle formed between a direction of the peak brightness of the light outputted from the light outgoing plane and a direction perpendicular to the light outgoing plane, and n is a refractive index of the light guide plate, and wherein θ is within the range 6-15 degrees.
