ABSTRACT:
A method and a parallel connection arrangement for equalizing the output powers of power converter units (INU11, INU12), in which power converter units is a semiconductor switch bridge controlled with pulse width modulation, andin which is a control unit arrangement (CU1, CU2) for forming control pulses, with which the semiconductor switches are controlled. The control unit arrangement delays the falling edge of the control pulses of at least one semiconductor switch of at least one power converter unit.
