Abstract

PURPOSE: To synthesize a PWM control signal for a 120°-energized inverter through a simple control circuit, by comparing a single triangular wave with one or plural reference waves.
CONSTITUTION: A comparator compares the triangular wave TRI with a reference level REF1 to produce an output C1, compares the triangular wave TRI with another reference level REF2 to produce another output C2 and compares the triangular wave TRI with still another reference level REF3 to generate still another output C3. These three outputs are applied to a logical circuit 4, which generates an output L as shown in Fig. The output L is applied to a wave form synthesis circuit 6 to obtain the control signal of wave form Th1∼Th6. The PWM control signal for the 120°-energized inverter is thus produced through simple circuits.
