A power converter having a dynamic bus controller to control a rectifier DC output for motoring and regenerating power flow directions, in which the controller controls a DC bus voltage between first and second regenerating voltage limits and limits power at the DC output in an increasing fashion with increasing values of the DC bus voltage according to a regenerating power limit parameter for a regenerating direction of power flow at a DC output. For a motoring direction of power flow at the DC output, the controller controls the DC bus voltage at the DC output between first and second motoring voltage limits and limits the power at the DC output in a decreasing fashion with increasing values of the DC bus voltage according to a motoring power limit parameter.

Linear and nonlinear dynamic bus control for AFE applications

An apparatus for an alpha trim adjustment includes a phase delay circuit that creates a phase delay for a gate signal for a switching cycle. The gate signal is for a phase of a three-phase, phase shifted alternating current ('AC') input of a multi-pulse motor drive powering a direct current ('DC') motor. The apparatus includes an alpha trim circuit that modifies the phase delay with an alpha trim adjustment to create an adjusted phase delay for the switching cycle, a delay application circuit that applies the adjusted phase delay to the gate signal.
