Abstract:
A new type trapezoid-wave PWM technique employed in VFVS ( varying- frequency and varying- speed) system was studied. The circuit principle and wave transformation as well as organization of sub- circuit are demonstrated systemically. Furthermore, the delta PWM inverter, the key unit in system, are also discussed in paper. Exper iment results show that the new technique has an ideal effect in harmonic wave suppression, high efficiency of energy conversion and advantage of smoothly conversion between constant torque and constant power.
