Circuit for a.c. current converter has two-pole stage in series with load that maintains large voltage for small secondary side current and small voltage for large secondary side current

摘要

The circuit has a primary winding (11), a secondary winding (12) and a load (3) for the secondary side. A two-pole stage (2) is connected in series with the load with a voltage and current characteristic that maintains a large voltage for a small secondary side current and a small voltage for a large current.
