Abstract
The disclosure relates to a capacitor arrangement for an input circuit or intermediate circuit of a voltage transformer comprising at least two capacitors and two connection nodes. Switching elements are provided, by means of which the at least two capacitors are connected in parallel with each other in a first operating state and are connected in series with each other in a second operating state. The disclosure also relates to a voltage transformer arrangement comprising such a capacitor arrangement and an operating method for a capacitor arrangement.
Claims13
A capacitor arrangement for an input circuit or intermediate circuit of a voltage converter comprising at least two capacitors and two connection nodes, wherein switching members are provided, by means of which the at least two capacitors are connected to the connection nodes in parallel with each other in a first operating state and connected in series with each other in a second operating state.
A voltage converter arrangement comprising a DC/DC converter and/or a DC/AC converter for a photovoltaic installation, the arrangement comprising a capacitor arrangement in an input circuit, output circuit or intermediate circuit thereof, the capacitor arrangement comprising at least two capacitors and two connection nodes, wherein switching members are provided, by means of which the at least two capacitors are connected to the connection nodes in parallel with each other in a first operating state and connected in series with each other in a second operating state.
An operating method for a capacitor arrangement comprising at least two capacitors and two connection nodes, and switching members, comprising configuring the switching members to interconnect the at least two capacitors in parallel with each other in a first operating state, and configuring the switching members to interconnect the at least two capacitors in series in a second operating state.
