Safety in industrial embedded system

You might start with reading ISO 12100, mother of all machinery safety standards, which I recommend to anyone trying to address machine safety. Then find out if there is a specific safety standard (...

Safety in industrial embedded system

As far as I can see, the EMG SWITCH is also used as an on-off switch. As for your questions, Is it better practice to use an emergency switch to drive a relay in this way rather than directly in the ...

Are inductors in resonant circuits dangerous? They produce very high voltages

It is true that at resonance, voltage across an inductor in a resonant circuit can be large...especially so if resonant components have high Q (quality factor). If one is building a power oscillator, ...

Are inductors in resonant circuits dangerous? They produce very high voltages

When you touch it, the human body will be adding capacitance to that circuit model, so it will quickly drop out of resonance. Thus, only the small charge in the cap at the time of touch will discharge ...

Are inductors in resonant circuits dangerous? They produce very high voltages

They can be, just like any circuit that generates high voltages can be dangerous, regardless of if it uses resonance, charge pumps, electromagnetic conversion, etc. Resonance requires specific ...

How can a Class E Power Amplifier be built and experimented with safely?

OP's circuit does generate voltage spikes at MOSfet drain that can considerably exceed the DC supply voltage. Switching current off quickly to an inductor is the cause. The circuit fragment of the few-...

How can a Class E Power Amplifier be built and experimented with safely?

basically be very carefull Follow the same advice given to those working with vacuum tubes. rubber shoes and one hand behind your back.

Does it improve safety to make a capacitative dropper symmetric?

I'd say it makes even more unsafe for variety of reasons. First of all, let's assume you live in a country where mains sockets and plugs are polarized and always wired correctly and there is never any ...

Does it improve safety to make a capacitative dropper symmetric?

If you use a circuit like this, then every node, before and after BR1, must be isolated from the possibility of touching it. Once that is done, it doesn't matter whether the capacitor is in the live ...

Are there safety concerns with hooking an inductor to a MOSFET and generating 85V spikes from a 9V source?

The breadboard will probably be fine, but anything above ~30VDC cannot be considered touch safe. In addition, the circuit you have does not regulate its output so the 85V figure could be low or high ...
