Dear Members
I am currently designing a static switch driver circuit (for thyristor based switch) for 1phase and 3phase AC supply. The same circuit will work for 1phase if jumper is not set and will work for 3phase if jumper is set.
The help i need is in switching off the thyristor. There are...
In a solar system during day power is obtained, but during night the same panel which acts as a power source act as load and will drain the battery. This is what most people say. And to avoid the power drain at night it is suggested to use a diode in series (Blocking Diode).
Now if i have a 12...
Dear All,
I am currently planning to start a open source hardware project. I wold like to licence my project under GPLv3 and i have a few query in the GPLv3.
This product i am planning is a solar charger
1) The hardware i am planning is open source (i will upload all the source and...
Dear All,
I am currently working on a design of Grid Tie Inverter where the source of power is from a Lead acid battery. The inverter converts the DC to AC and will feed it the Grid.
In low power range of less than 200W boost converter are used to step up the DC and then convert...

So that being said i am currently in the part of the design stage where i need to choose the...
I have always been a fan and user of open source software. But being a hardware engineer it has always bugged me there need to be open hardware too, just like software.
And there are, like "arduino", "raspberry-pi" etc, but all seem to focus on prototyping. I am looking for some open hardware...
I am not sure if the topic fits here. Is there any microcontroller forum here?? [ponder]
Any ways i have my PIC16F685 on which i have watchdog enabled and it works fine and resets the pic on time out, but once i enable the GIE or PEIE (that is the interrupt - timer 1 actually) now the watchdog...
I am currently involved in a project where data needs to be exchanged between a device with wifi capability and a microcontroller interfaced to a wifi module. The choice of wifi module is RN-171-DS. Its chosen for cost and simplicity.
(If anyone can suggest a much better module at low cost...
I have a relay design, where the relay switches AC 240V/10A (Phase Line). Sometimes during switching the LCD on the board goes blank. Similar problems have been reported on various other forums too.
Suggestion was that the switching of the relay produces spikes and a snubber cap of 0.1uF/1KV...
I am implementing a MPPT solar battery charger (buck converter). The type of converter design have been discussed in my previous post http://www.eng-tips.com/viewthread.cfm?qid=350101
I have finally decided to implement a Interleaved buck converter with 4 leg. With separate driver and mosfet...
I am designing a MPPT solar charge controller (buck mode) to charge batteries from 500 Watt solar panel. As per my calculations i need 50uH inductor with current rating of 50A for 12V battery.
My problem here is getting an inductor for 50A rating as it will be big and bulky.
The solution i...
