USING VARIABLE IMPEDANCE TO KEEP UNDER-LOADED ELECTRONIC TRANSFORMERS DELIVERING OUTPUT POWER

摘要

A sub-circuit for keeping under-loaded electronic transformers delivering output power, includes connectors (AC1,AC2) configured for connecting the sub-circuit to the transformer and to the powered circuit. The sub-circuit includes a Delon doubler circuit (D1,D2,C1,C2) that is connectable to the transformer via the connectors (AC1,AC2) and that is configured to supply DC to an output of the Delon doubler circuit (D1,D2,C1,C2); and a current regulator (1) connected to the output of the Delon doubler circuit (D1,D2,C1,C2). The current regulator may be a linear (1) or a non-linear (2,3) current regulator.
