Abstract

This paper presents an implementation of space vector pulse width
modulation signal generation for driving three phase voltage source
inverter. The SVPWM technique gets the PWM switching times for
the inverter legs directly from the sampled amplitudes of the
reference phase voltages. The SVPWM switching strategy is based on
the right aligned sequence. This method is much simpler and more
executable than conventional means without look-up tables or
complex logical judgments. The SVPWM scheme is
modeled/simulated using MATLAB SIMULINK software package,
and experimentally implemented / verified on the low cost microchip < br />8 bit microcontroller PIC16F747 platform. The experimental results
are presented for three phase two-level inverter followed by three
phase output LC filter.
