One guide is that a device which is affected by supply voltage changes (or droops) should be given its own stable supply.
Conversely loads which change suddenly (have the effect of creating voltage droops elsewhere) should be on their own supply.
Led's don't light at all unless applied voltage...
I've not worked with IGBT type but if their bias is like ordinary transistors you need greater than supply_V at bias to turn on N-devices. Likewise P-devices in symmetry because to shut them off they need bias voltage identical to supply_V. Since you speak of pulses it suggests you wish to...
You can get a clue from ampacity tables which list a safe Ampere level for a single wire or wound wires. Somewhere is a formula telling what level makes a given gauge 'too hot'.

There's a saying:
'Analog make many sell many.
Software make one sell many.'
More and more projects use digital instead of analog. Components for electronics are getting so miniaturized that hobbyists have trouble working with them. 13 years at this forum and we've observed a growing...
My reason may already have been implied in above replies. Your problem could be that high-freq oscillations spring up after any (conductive, capacitive, static charge?) touch.
Your circuit powers up okay and works okay, however once they begin such oscillations tend to continue. Volt readings...
Although CST is a frequent topic here at Edaboard, it's usually associated with electromagnetic components rather than magnetics. Electromagnetism is not the same thing as magnetism. (Even an electro-magnet and electromagnetism are similar words but different principles.)
Transformers generally...
The arrangement of the two transistors is a convenient method by which a weak signal is able to control a P-device (Q2). And R2 is necessary to provide Q2 bias with a reference to supply voltage. This allows the P-device to be biased with a definite voltage which has some shutting-off effect, in...
I think the heart of your experimental approach is similar to making an old-fashioned 'crystal' radio. These run on no batteries yet harvest a broadcast out of the air and play it in headphones, all using power from nowhere but the airwaves. Suppose you place a simple coil near your simple radio...
The running amount is one item yet as Klaus points out (post #2) current is admitted as brief strong bursts at each voltage peak. Following your schematic I made a simulation. I adjusted values to result in providing +12V -12V. Current draw approximates your spec loads. Each burst is over 6...
Simple textbook method to pass or halt a digital signal...
Plain AND gate: Pull one input high when you wish to pass the other input.
Add a second gating system if you need to choose either of two signals.
Circuit diagram:
I saw one article telling how it can be and is done with a single brief burst of opposing voltage at the thyristor terminal (current-carrying terminal). This stops current flow through the device by the identical manner which textbooks describe a thyristor shutting off. It's hard to wrap one's...
There was a previous thread about this topic. One or more daily experts here stated the capacitor input filter is sufficient in most cases (for real life). Certain power sources (batteries) seem to have slight inductance built in. So usually the resistance in power supply hookups is sufficient...
You may find a CAD-based simulation out there to guide you. One big difference is whether a coil has a core of air or of metal. A metal core attracts and concentrates flux so it's hard to be sure what sort of invisible field extends out of the inductor.
My own home-brew simulator might offer...
Over a kW...My quick search leads to websites that present wireless charging of industrial batteries. The idea appears legit although power transmission at high levels seems too good to be true. Wireless charging promises so much and is in such huge demand, yet even today we need massive cables...
