ABSTRACT:
The invention describes a method of regulating a rectifier inverter system (1), whereby electrical power is generated and/or supplied via a power source (6) and is transmitted from at least one d.c.-to-d.c. converter (3) to an intermediate circuit (4), from where it is fed via a d.c.-to-a.c. converter (5) to an alternating voltage supply (8) and/or delivered to a consumer. The d.c.-to-d.c. converter (3) is regulated in such a way that a virtually constant current flow is applied from the input of the d.c.-to-d.c. converter (3), in other words from the power source (6), to the output of the d.c.-to-d.c. converter (3), in other words the intermediate circuit (4), during a pre-settable period irrespective of the power drawn off from the intermediate circuit (4), whereas during this same period power is drawn off from the intermediate circuit (4) to feed it to the alternating voltage supply (8) or deliver it to the consumer. A controller or a control system of the d.c.-to-d.c. converter (3), in particular a desired value for regulating the current flow through the d.c.-to-d.c. converter (3), is re-set whenever the period elapses.
