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.
Method of regulating a rectifier inverter system, whereby electrical power is generated and/or supplied via a power source, in particular via at least one solar module or via a battery, which is transmitted from at least one d.c.-to-d.c. converter to an intermediate circuit, from where it is fed via a d.c.-to-a.c. converter to an alternating voltage supply and/or delivered to a consumer, wherein said d.c.-to-d.c. converter is regulated in such a way that an almost constant current flow is applied from said power source, to said intermediate circuit, during a pre-settable period irrespective of the power drawn off from said intermediate circuit, whereas during this same period the d.c.-to-a.c. converter draws off power from said intermediate circuit to feed it to said alternating voltage supply or deliver it to said consumer, and a controller or a control system of said d.c.-to-d.c. converter, in particular a desired value for regulating the current flow through the d.c.-to-d.c. converter, is re-set whenever said period elapses and an adaption is made for a successive period at times wherever a preceding period elapses.
Rectifier inverter comprising at least one d.c.-to-d.c. converter, an intermediate circuit and a d.c.-to-a.c. converter, to which a power source or a power generator, in particular a solar module, and/or a battery can be connected and the latter can be connected to an alternating voltage supply and/or one or more consumers, wherein said d.c.-to-d.c. converter is configured so as to supply an almost constant current flow for a pre-settable period irrespective of the power drawn off from said intermediate circuit by said d.c.-to-a.c. converter and, when said pre-set period has elapsed, a desired value or a desired current of said d.c.-to-d.c. converter can be adapted to the power drawn off from said intermediate circuit by said d.c.-to-a.c. converter and an adaption is made for a successive period at times whenever a preceding period elapses.
