Abstract
A method for controlling regenerative energy in a system having an motor and having a power converter for converting regenerative energy from the motor for supply as electrical current to a receiving apparatus includes estimating a resistance to electrical current flow between the electrical power converter and the receiving apparatus and measuring a first voltage at the receiving apparatus. The method further comprises controlling a regenerative current from the power converter to the receiving apparatus in view of the resistance and the first voltage to limit a second voltage at the power converter.
