AN4993 Application note How to implement an SCR or a Triac in hybrid relay applications Introduction This document gives some key information about the design of the solid-state silicon AC switch stage of a hybrid relay, which can drive resistive, capacitive, o...
Key takeaways: • Know the principle of suppressing oscillations with passive snubber circuits • Learn how to design a Flyback RCD snubber circuit based on analysis and example demonstration • Receive a brief introduction to the operating princip
Designing reliable, efficient, and fully-featured power supplies requires expertise across multiple engineering domains coupled with practical experience guiding design choices. A structured approach allows methodically addressing requirements and making sound trade-offs from topology selection to packaging. Utili...
Such disturbances may also couple with other near wires, leading to bad performance and possibly also failures. Figure 13. Worst case for conducted emissions: switching an inductive load without a snubber for recirculation GADG2509171305PS AN5084 - Rev 1 page 10/33 AN5084 Example of...
No matter how you want to control power sequencing and on-off timing for your devices, you can create and evaluate your circuits with the complete set of simulation tools inPSpicefromCadence. PSpice users can access a powerful SPICE simulator as well as specialty design capabilities like model ...
Figure 13: An RC snubber of the SSR output prevents false turn-on due to inductive loads. (Image source: Omron Corp.) The situation for DC SSRs is similar but somewhat simpler. If the load is inductive, the current spike it generates when it is switched off can damage the now open ...
At the zero-crossing point of the AC sinusoidal waveform, the AC type Solid State Relay turns “ON” and it prevents high incoming currents. While switching high capacitive and inductive loads, RC Snubber circuit is used to eliminate the noise and voltage transient spikes. As the output switchi...
resistance. Unlike the simple 555 timer flyback drivers, The ZVS flyback drivers will allow you to run your flyback transformers for much longer periods of time before the MOSFET's overheat. If you get really good MOSFET's, it might be even possible to run your ZVS flyback driver ...

Rsnubber in the RC snubber circuit should equal Zchar above, and the capacitor, Csnubber, should be sized to be multiple times the parasitic capacitance, CPAR. A factor of about 7x was chosen for the measurements in this document. The measurements for each of the steps above can be found...
