I need a simple DC-DC converter to obtain 12V voltage from a variable DC input voltage. Please don't offer me to use a SMPS topology, because this 12V DC itself will be powering a Buck converter IC. This 12V will be powering this Buck converter IC and a few opamps; I presume that the load...
From the very start I insisted on making a completely solid state design. But looks like the hardware design challenges are pushing me to use standard relays once again.
I wish those SSRs weren't that much expensive...
Circuit explanation:
When you first power up your circuit, C1 starts charging up over R1. When the voltage on C1 reaches to enough level ("enough level" is the voltage that is enough to trigger the thyristor or triac. Refer to its datasheet), the thyristor conducts and starts to charge up C3...

I'm designing a power supply. Main power source is a transformer. The transformer has multiple taps; 9V, 15V, 24V, 36V, 48V. For obtaining as much efficiency as possible, a control circuit is monitoring the output voltage of the power supply and switching between...
Ok, I will try that configuration now...
My current circuit is like this:

All I'm trying to see is that, a 5Vp-p pulse in primary windings is directly transferred to the secondary windings (of course there will be some loss).
After a little research I learned that a...
I tried connecting the MOSFET to the lower side too, but it didn't make very much change.
I used "Microsoft Visio" for entire drawing.
That's n-MOSFET in my circuit, I used the wrong symbol in the schematics.

I'm designing a switch mode power supply which can be described by the block diagram above. The pulse generator circuit consists of a 555. Output of 555 is directly connected to the gate of the MOSFET (6N60). A 100Ω resistor is connected to the secondary windings of the...
