This paper designs and implements a DSP-microprocessor based variable frequency motor drive.
We control the induction motor with V/F scheme. This paper also analysis about Sine-PWM and
Space-Vector-PWM. Compared with commonly used SPWM method, SVPWM has the advantages
of higher voltage utilization, lower harmonic and lower switching loss. Also, it increases the efficiency
of an inverter. To calculate duty cycle this paper support different update model, so symmetrical and
asymmetrical PWM are generated. To analyse about spectra, and we can find the asymmetrical PWM
restrain the harmonic.
