20 mar 2020 · To do that you would need to measure the capacitance between the live feed and the switched wire and also the voltage at which the lamp does not light at all. I think the 0.22 uF suppressor will probably work. It will depend on how long the power feed and switch wire run close to each other.
26 cze 2013 · For minimum magnetic surge current, you switch on at a voltage peak - this way the AC wave averages to zero in a mere half cycle. To make a transformer that does not surge with random switch on points,
1 lip 2017 · The other solution would be to remove the LED screw-in and either leave no bulb there or put the incandescent back BUT mount an LED strip (either motion sensitive or switched) mounted to the bottom of the microwave which would give much better light and would turn off.
26 kwi 2022 · There are two reasons for the light and fan to keep running in a microwave. It is either faulty door switches or it could be the control panel. The door assembly, like a broken latch, could also be to blame.
30 lip 2018 · For a switch with ohmic contacts, the lower frequency boundary of its bandwidth in an ON condition is direct current (DC). Capacitive switches do not pass the direct current. The upper boundary in an ON condition is defined by spurious circuit parameters introducing transmission losses.
DC dissipation of switch elements. FETs require only a voltage signal for switching, instead of a DC current. This means that they have essentially zero DC power consumption, compared to the 10 mW or so it takes to turn on a PIN diode.
Driver requirements: the driver circuits for PIN diode switches and FET switches are quite different, since the former requires a DC current while the latter requires a DC voltage, usually negative polarity.
