Choke power supply- part 2

The schematics above are 6 types of ways to do choke regulation. The big inductor after the bridge has wicked overshoot but eventually settles. Normally you put an element across the inductor. Note all the voltages are less than the capacitor alone. That is the load dependency issue with choke supplies. The one that overshoots a little and then settles fast with little ripple is a hybrid of inductance before the transformer and after the bridge. Hybrid approaches are best.

Sorry it is hard to read. Not the easiest editor with embedded images.

If you really want to learn more a about choke applications in power supplies find yourself an amp tech that worked on Fender amps from the 40’s and 50’s when Leo was going for cleaner and cleaner tone. Short story to effectively use choke tech I t requires massive high quality transformers which is a cost and supply chain issue. Unless you take the McIntosh approach and produce them in-house.

We use chokes in our designs more expensive well yes a resister can cost $0.99.  I have seen preamps that use a resistor to stabilize power.  But the average person here does not have a clue.
