description The invention is related to a method of initiating a regenerative converter (1) for supplying electrical power to an electric motor (10) of a hoisting machine to drive an elevator car of an elevator system. The invention is also related to an elevator system comprising an elevator car, and a hoisting machine comprising an electric motor (10), the hoisting machine arranged to drive the elevator car of the elevator system, and said regenerative converter (1). The method comprises charging, through the line bridge (2) and while the machine bridge (3) remains inactive, the DC intermediate circuit (8A, 8B) to a target voltage (14) higher than peak value of the mains voltage (13).
