Abstract
The present invention relates to a multichannel test system () and to a method for supplying test load devices () with electrical power from a supply grid, comprising at least a first test channel () and a second test channel () which are galvanically separated. At least one switching device () is provided for galvanically coupling intermediate circuits () of the test channels () in a switchable manner to form a common intermediate circuit. For this purpose, in addition to phase-controlled, variably adjustable rectification, uncontrolled, invariable rectification is also provided in a passive operating mode by an active power stage () in power converter circuits () of the test channels ().
