Posted on July 19, 2013 at 05:44How to Control the SCR with Microcontroller. I dont want to mix the Digital Signal Ground with the High Voltage Ground. But the SCR will need the Gate current in uA w.r.t its Cathode. But I couldnot connect the Cathod...
Snubberless triac and need for external snubber circuit.
Posted on March 08, 2015 at 12:10 I have simple question about snubberless triac. When it is said that the triac is snubberless do still need an external snubber circuit?
Triac triggering circuit with a positive power supply
Posted on December 01, 2016 at 00:27 After reading AN3168 I found a paragraph that I do not actually understand and seemed weird for me . Page 8, ''With the bipolar solution, to keep the current sourced to the gate, the only way is then to use a PN...
Increase the Power capabilities of STEVAL-ILD004V1
Posted on October 12, 2015 at 20:29I need to support a 2-wire 500W dimmer instead of just a 300W dimmer at 110VAC 60Hz US. What are the power limiting components of the ST Dev Kit? The 2 1N5404 diodes are only rated for 3A which would be 360W. Is th...
