a two-transistor forward converter has two outputs -
15V and 24V. The two outputs have coupled output inductors. Please explain how the coupled output inductors improve
the output cross regulation, reference preferred.
Hi, a coupled choke avoids the need for seperatechokes for each aux output, reduces the number of turns required and simplifies preloading. The turns for each choke are in the same ratio as the main transformer.
The information provided is good, but the question is not
answered - how the coupled output inductors improve the
output cross regulation,,,
With separate inductors, the load of one output increases will result in the voltage increase of other output.
With coupled inductors, the voltage increase of other output should be smaller, WHY?
