Abstract

See full text

The present invention relates to a multichannel test system (100) and to a method for supplying test load devices (61, 62) with electrical power from a supply grid, comprising at least a first test channel (10) and a second test channel (20) which are galvanically separated. At least one switching device (40) is provided for galvanically coupling intermediate circuits (13, 23) of the test channels (10, 20) 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 (12, 22) in power converter circuits (16, 26, 36) of the test channels (10, 20, 30).
