| Abstract |
This work proposes a new switching scheme for cascaded multilevel inverter. The scheme is based on
symmetric regular sampled unipolar PWM, with multiple modulating waveforms and a single carrier.
Mathematical equations that define the PWM switching instants are derived and implemented digitally using
a low-cost microcontroller. A five-level cascaded multilevel inverter test-rig is built to prove viability of the
proposed algorithm. |
