110AC to 140DC? Answered

I've got a 140VDC motor from an old garage door opener.  I want to use the motor for another purpose.  The original controller board is fried.  Will a bridge rectifier that can handle 110AC over power the motor?

Use a Prius as Aux. A/C Power Generator

We saw a story about someone that claims to have hooked up their Prius' electric motor batteries, through a AC Converter of some type, that converts the 200+ DC volts in the Prius main batteries into 240 (or 110?) AC power that can be feed into your house. See the following URL: http://www.wikihow.com/Use-a-Toyota-Prius-As-a-Backup-GeneratorReading it here vs. having someone really "tell all" about doing this for real, including the sources for the converters, etc. is what is missing. We have occasional power outages and our house gets cold in Washington State. Using our Prius' ability to self-regulate it's batteries seems like a great idea on getting more value out of this car.Come on your tinkering experts.... show us how to really do this.Rick

Tripping a Breaker

Hello. I need help with charging a capacitor bank I have. It consists of 10 capacitors: 4 4700uf capacitors and 6 6800uf capacitors. All are wired in parallel. I have been charging them with 110AC rectified to DC. The only problem is that whenever I flip the switch to start charging, it trips our shop's 20A breaker and you have to flip it back to start charging again. It trips our breaker every time and dims the lights making my dad angry. So I need some tips on what wattage resistor i need to use to keep from tripping the breaker. I experimented with a 10W resistor and that was way too much resistance. I am not allowed to experiment anymore until someone credible can tell me what to do. Thanks for your help.

how can a phoneline have both ac & DC?

Our phone lines have static, a friend told me to check to voltage (for ac to see if the cordless phone was the iussue) I check and the line has 110AC and about 52 DC. I unplugged the cordless phone and still get the ac voltage. most of the phone jack boxes show the dual voltage, but I have found one that only shows the DC, and no AC what so ever. How is this possible?

I have some questions on bridge rectifiers and how they work/output current and voltage, see details for full info.

If I use a bridge rectifier to convert AC 110V into "DC" 110(154V), I'm guessing the amperage rating on the rectifier is how much current will be available to use vs the voltage being output as well? The reason I put 154 volts is because peak voltage is 110ac times 1.4. I'm using this for LEDs, just to provide some more info. The bridge rectifiers I have are rated at 200V and 1.5A.?

Ok, I need a diode bridge to change 110 ac to 110dc.. So I plug it in and go..

Hi Everyone,  I really need some smart person with common sense to answer this... I just want a very simple easy way to plug into a wall socket and transform the 110AC to 110DC...I will be using this for a very large hydrogen generator... very low amp draw.... I know I need a diode bridge with maybe filters before and after the bridge...   So, now I need to put that together... I can not find a site that has one premade...   So, I would be very appreciative to anyone that can offer a web site for parts with part numbers and a diagram or instructions to put it together..   I am a Journeyman Carpenter for anyone that needs advice..  Thanks in advance.    I would be willing to purchase it from anyone that wants to make it for me.. Bryan
