Delay in discharging of the capacitor for sequencing purpose
Our aim is to sequence 2 different power supplies i.e. 5 V and -48 V.
On sequence is first "5 V is generated" and then "-48 V is generated" with 120 ms delay.
Off sequence is first ...

IGBTs fail after high current, high voltage switch, despite being lower than absolute maximums mentioned in datasheet
I'm using FGH60N60 IGBT as a switch. The circuit is basically a capacitor-discharging circuit. I have a 10 mF capacitor charged to 310 volts and connected to 2 Ω of load via this IGBT (I connect 4 ...

Connecting two Li-ion batteries in series, with different capacity
I'm going to start by saying this is an "emergency", because the delivery of my new battery cells are delayed.
I have two 3S Li-ion batteries: one with 2250 mAh (50 C) and the other with ...

When discharging a capacitor, why would a resistor make a difference if it is situated after ground?
So I am currently analyzing RC circuits in my textbook, and, just out of curiosity, I conjured up this circuit on Multisim to charge and discharge a capacitor using a SPDT switch. This first circuit (...

Why are life cycles used as a measure for battery health?
I was curious on how the depth of discharge for batteries affects the battery health as I've heard never to let your phone go down to 0%.
I was searching online and every paper I found on this topic ...
