    Great to build 3-phase inverter too!

    Posted by Marc Perron on 28th Nov 2017

    Thanks Digilent, We have used this product to demo our 3-phase PWM IP Core product with a BLDC motor. By using 2 PMOD dual bridge components, one can actualy build a 3-phase inverter to drive 3-phase loads such as a BLDC. Here's a one minute demo of the result. Best Regards, Marc Perron, Ph.D., ing.
