Voltage control method and an electric motor control system
A method for controlling regenerative energy in a system having an motor (10) and a power converter (14) for converting regenerative energy from the motor (10) for supply as electrical current to a receiving apparatus (12) includes estimating a resistance to electrical current flow between the electrical power converter (14) and the receiving apparatus (12) and measuring a first voltage at the receiving apparatus. The method further comprises controlling a regenerative current from the power converter (14) to the receiving apparatus (12) in view of the resistance and the first voltage to limit a second voltage at the power converter.
