Regenerative Bus Supply Configurations With Active Shunt
This system also uses a PWM-controlled IGBT converter for regeneration of power to the AC line. However, in this configuration some
regenerative DC-bus energy flows to the incoming AC line, but DC-bus energy that is not regenerated is dissipated to an external shunt
resistor (braking) unit. This configuration provides low AC-line harmonics and can be used to meet IEEE-519. Contact our Encompassâ„¢
Partners for these shunt resistor (braking) products.
Supported Products
At the time of publication, the following products are supported.
When applicable, the drive's internal IGBT can be used with a passive shunt.
