Jun 7, 2015 · Hi, Old circuit idea for ZCD, I wanted to see if it could actually be used in the real world (and how to go from sim-world AC generator version to a practical implementation). …

Jul 26, 2017 · On the diagram on page 315 of micro datasheet, there appear to be two current sources which act sop as to regulate the ZCD pin to 0.75V. Is this true? Presumably at the …

Jun 7, 2015 · When I connect the peak detector circuit to a zero crossing detector circuit - the ZCD is there so as to discharge the peak value capacitors periodically - the negative peak …

Oct 4, 2018 · What is the exact use of zcd circuit in dual converter using thyristors ? Is it used for generating pulse or pulse can be generated using by PIC itself ?

Jul 7, 2018 · However, the ZCD pin voltage must rise above 1.4V so that the ZCD pin is again “armed”. –But supposing that the ZCD pin has not risen above 1.4V when the current sense …

Aug 30, 2008 · What I wanna ask, when you want to speed up the motor? the time to fire TRIAC is shorter or longer after zero crossing deteced? The shorter the firing delay after ZCD, the …

Feb 15, 2002 · So by using the ZCD method, the buzzing sound from the triac does not seem to occur. I have tested the ZCD method on a 85W motor and it works fine for more than 1 hour …

Jun 13, 2021 · Hi, We need a zero cross circuit which gives a falling edge 430us +/-50us before the zero cross. The attached is the best we can come up with. Do you have better? Its for …
