clean 9.6 volt DC at 5.0 amps from varying 18 to 90 VAC source
clean 9.6 volt DC at 5.0 amps from varying 18 to 90 VAC source
(OP)
Need to design a circuit to provide avionic clean 9.6 volts DC at 5.0 Amps. regulated, from a varying AC source of 18 to 90 VAC (alternator) Need short circuit and shutdown protection for output over-voltage or current with a reasonably quick risetime response and recovery rate. 10Ms?
The device will be used to power GPS and low-power aircraft VHF comm radios on light aircraft that do not have a battery.
In trouble here-Haven't designed any circuits since 1965!
Need all suggestions and current/application/component source info and suggested circuit ideas I can breadboard and analyze. Thanks!

Automotive applications are VERY demanding and require significant work to make them effective for all possible conditions. Why don't you simply use a standard OTS regulator with a protection zener clamp (around 20 V)on the front end? I have found that a simple LM323 with a good 12W heatsink work well in all of my designs.
Just an idea. Keep us posted!

It's a tough design given the input voltage range.

It normally takes several years to become proficient at switch-mode power supply.
