the problem is that I'm making a reliability prediction analysis with the IEC TR 62380 standard and for integrated circuits it distinguishes between MOS, Bipolar and BiCMOS circuits and in this categories it is possible to choose between linear, digital, linear/digital,...
the step-down swtiching regulator LT1376 is to consider as a linear circuit or as a linear/digital circuit? The block schema in the datasheet as a SR flip-flop so I think that it has to be considered as linear/digital circuit.
calculating power consumption of op amp
to calculate the power dissipation in a op-amp where the positive supply voltage is 12.25V and the negative supply voltage is 0V is it ok to multiply the positive supply voltage with the current drawn from it?
Has someone of you already used the TI model provided for PSpice? I downloaded it and tried to simulate the comparator by having a voltage at the non-inverting input larger than the one at the inverting input but the output is always near 0V.
Here the model...
It is a gate driver unit for 6.5kV IGBTs. On the lower left there is a "big" voltage divider needed to measure the voltage between collector and emitter.
I found some of the components looking at SMD marking code databases, but I couldn't find everything.
identification of electronic components
I'm analyzing the circuit shown in the image and I need to recognize the 3 marked elements. The T27I is a diode but I have no idea of the manufacturer. The other two components have a SOT23 package and are marked with A7 9(rotated of 90°) and W9C...
Re: design of gate drivers
yes i also thought about using a pulse transformer with two outputs isolated from each other and to make it simpler i decided to use two isolated dc/dc converter from TracoPower which are small and efficient.
design of gate drivers
I need to design the gate drivers for the 2 swiches (S1 and S2) on the secondary side of this circuit.
They are two bi-directional switches with this topology.
The source potential is floating so I need a supply that gives the needed voltage (in this case 10-12V)...
calculate series resonant capacitor
i found this capacitor **broken link removed** i can use 10 capacitors 22nF/2000VDC/500Vrms to obtain 0.22uF but there is no mention about the current. Another question is if it's reasonable to have so many capacitors in parallel...
series resonant inverter
Hi, I'm trying to build an inverter that uses series resonance in order to achieve soft switching, the problem is that I need a capacitor of 0.33uF that can withstand a voltage of 320Vrms at 50 kHz. I have not much experience and I couldn't find any capacitor that could...
