#99859 - Google on current sensing resistor and t Responding to: ???'s previous message |
If you see most new TCS( thyristorised capacitor switch) use ZCS (zero current cross ), hence I need to know how could I detect a current cross.
Should I convert current to voltage and then use same method as a zero voltage cross?or there is any other professional way ? Google on current sensing resistor and then select the proper value, they come down to milliOhms. This gives you the very convenient voltage sensing. Erik Just strikes me: how can you detect zero curren when the triac is off (+no corent) ? |
