The Ride-Thru Impedance Module provides the necessary impedance to prevent the
propagation of circulating currents between the variable frequency drive and the Ride-Thru
Module. Stray circulating currents cause heating in the components of the Ride-Thru and the
variable frequency drive. The addition of the Impedance Module adds a fixed voltage drop in
the negative link in the connection between the boost regulator and the drive. Please see
Section 7 for further details.
