AC Cap Dropper DC Power Supply

Anyone know of a clever way to regulate other than  the typical
brute-force zener clamp?

I love to cook with wine.     Sometimes I even put it in the food.

A long,long time ago in a place not so far away I used a transformer made by Sola that had a matched resonant capacitor. Tom

Will it fit in 1" x 1" ?:-) ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

Not hardly. And it was heavy too. Tom

Will it fit in 1" x 1" ?:-) No, but that VR method marches on (for select applications). http://www.generaltransformer.com/transformer/ferroresonant-transformers.htm

I remember them. Nice scheme if you stand the space/weight. ...Jim Thompson -- | James E.Thompson, CTO | mens | | Analog Innovations, Inc. | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | Phoenix, Arizona 85048 Skype: Contacts Only | | | Voice:(480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

If your looking for a junk don't care 120V low current supply.. this works on the starting cycle and uses only a portion.. it kinds of semi regulates, it's only good for low current.. 120V AC || +-------+-------------+-||-GND | | || | V | - 0.1uf --- | --- | | |/ |---------+-| 2N5550 | |> | | .-. | 2k | | | | | +----------+ '-' | |+ | 500u --- | === --- .-. GND | | | | | | Your Load === '-' GND | | === GND (created by AACircuit v1.28.6 beta 04/19/05 www.tech-chat.de) Like I said, it's junk but it works, you can sim that ... I think that was around 5 volts out.. Jamie
