with Jim Williams video.linear.com Linear regulators are commonly employed to post-regulate switching regulator outputs. Benefits include improved stability, accuracy, transient response and lowered output impedance. Ideally, these performance gains would be accompanied by markedly reduced switching regulator generated ripple and spikes. In practice, all linear regulators encounter some difficulty with ripple and spikes, particularly as frequency rises. This video, excerpted from LTC Application Note 101, explains the causes of linear regulators' dynamic limitations and presents board level techniques for measuring and improving ripple and spike rejection.

This is a short video of the early testing of my new GAVR-15 AVR on my ST-10 Generator. You can see clearly it self starts easily with no capacitor or ballast required. The voltage regulation is nothing short of excellent, even handling a large bank of fluorescent lights on their own with no noticeable flickering. The other regulators I have tested have all needed an additional load such as a heater or similar before they could make a stable voltage while running these lights. This shows how well filtered this regulator's circuits are.

Power Failures

Power FailuresWe can recently hear the word combination "power failure" quite often. But what kind of failures are there? How are they different? Let's try and look into it.The first and most common power failure is brownouts, that is short-term voltage depressions associated with a rapid increase of load in the network caused by connection of powerful consumers, such as, industrial equipment, elevators, etc. This is the most common failure in a power network. Such failures may result in overloads of power supply units, disconnection of devices, failure of electric motors, data loss in computers. High-voltage pulses - short-term (nanoseconds or microseconds) significant increase in voltage caused by a close lightning discharge or supply of voltage at the substation after an accident. High-voltage pulses may result in failure of equipment sensitive to the quality of power supply.Complete power outage is a result of an accident, lightning discharge, significant overloads at substations. This usually results in data loss in computers and failure of hard drives.Excessive voltage - short-term increase of voltage associated with disconnection of powerful consumers or with the total underload in the network. Results in failure of equipment and emergency outage of equipment with data loss in computers.Unstable frequency is a result of strong overloads of the energy system as a whole. The change in frequency in itself does not imply any significant danger. But it could lead to ...

Virtual Remote Sense

with Robert Dobkin, Vice President of Engineering & CTO video.linear.com Compensating for unknown wire drops without remote sensing wires is now possible. The LT4180 continuously modulates the power supply output current to interrogate the line drop. Then the output is increased to match the drop providing up to a 50 to 1 improvement in regulation at the load.

I decided to try and make a 12V, 5V, 3.3V DC power supply from the junk box. This is the result. Total cost under $5. I used a large load resistor to pull up the supply voltage and stabilize it. For a little more I could have added a voltage regulator. This one should run 10 amps all day long, max of 20A on 12v, 26A on 5v. That ought to charge your iphone!

Its just as simple as adding a resonant capacitor across the primary of the flyback (in my case it was about .20uF) and adding an inductor of some kind in series with the + and the primary of the flyback. The next step is a half bridge. But thats after I get my second breadboard. All I need to do now, is get my breadboard, add a 12 volt regulator for the 555 timer, and get a .22uF capacitor *more than 250 volts!!!*
