Описание к видео Video #2 ABB ACH580 Variable Frequency Drive PWM Design Theory

This is video #2 of a series on ACH580 Variable Frequency Drive Training offered by Borie Davis Inc., your HVAC ABB Drives Representative in the state of Georgia since 1981. This video shares with you a basic understanding of the construction of the ABB variable frequency drive, physically, and electrically. The basic math associated with mechanical and electrical control of HP, Torque & RPM offered in video #1 will now be applied to make up the PWM design theory that shares with you how this is accomplished.
