Circuit arrangement for use in testing and measuring amplifier to parallelly connect alternating voltage sources to common load, has terminals that are attached to one of voltage sources and arranged at distance from common winding terminal

摘要

The arrangement (3) has a transformer (4) comprising two partial windings (5.1, 5.2) which are arranged in series with one another and are connected with each other over a common winding terminal (6). A load (L) is attached to the terminal. Winding ends or terminals (8, 9) are attached to one of voltage sources (2.1, 2.2) or at a common winding terminal of another transformer, where the terminals are arranged at a distance from the common winding terminal. The winding ratio of the windings is selected corresponding to a desired distribution of the current supplied from the sources.
