Hello John
That�s means Bridge isn�t only amplifier. Actual construction include in it some rectifiers elements. The differences between Bridge and Half-bridge is that in Bridge we use both of sides sinusoidal wave and in H-bridge there are remake only one side of this wave. (is that completly correct?) Is there are any other general differences? This is general very often used bridge for controlling a Brushless motors: http://www.mskennedy.com/media/documents/4357ri.pdf http://www.allegromicro.com/sf/8904/ Regards.

What you may not know is that there is no intelligence in the power block. It just contains a rectifier and 6 power transistors. The major complexity of either a VFD or a servo drive is the control logic that generates the signals to drive those transistors.
