Genome, do you think is the inductor problem? The output voltage from the secondary is normal. But I keep getting the capacitor voltage same as the secondary voltage. I left 1 week to complete the circuit. Please give me some suggestions.
I think the noise is come from the sparks. I do no know why when I connected the probe to the output capacitor, there are sparks. I think my component spoilt because the output voltage of the capacitor is same as the output of secondary transformer. It is weird.
I have checked..It is the capacitor's problem. However, when I tried with 42Vac, I can hear some noise. The noise is like "tik tik tik". Is it come from MOSFETs?
As for the 1 Ohm resistor, the current is about 1A with 42Vac.
I'm so so sorry. I have wasted your effort. I'll try go and ask again. From where you sent the parcel?
By the way, I would like to ask do I need heat sink for the mosfets for the circuit?
For the transformer to step down from 240V to 48V, you mentioned that the voltage will drop to 24V due to...
Yea I know the breadboard and polystyrene will no work out. I just test them at low voltage.
What is the Veroboard? It looks like strip board. Can it stand 240Vac?
Sorry, I still not yet receive the parcel. :sad:

Genome, where is the Va and Vb?
All components I connected them through breadboard and polystyrene. Now, I would like to test with higher voltage. Can a breadboard stand that? Or do I need to do PCB first? Can a normal PCB stand 240Vac?
I had tried..It seemed no difference. When I tried with higher voltage, the voltage drop is less. So, I think it should be ok. I would like to ask if a square wave signal after the two switches drop to negative. Is there any problem? Before the two switches, the output is DC so after the two...
Genome..For the converter circuit, is it necessary to use the resistor parallel to the capacitor. I had tested the circuit. There is large voltage drop from 5V to 1.4V. Can I just take off the 2 resistors and use 2 capacitors only?
Thanks Genome. I'm more clear with the windings now.
For the regulating, do you mean that the regulator itself will change the pulse width when driving the MOSFET?
Genome, why the ripple current values for both pictures shown have so much difference? When will the inductor current be...
Hi, Genome.
How the output 72V will drop to 24V since the pulse width is 50%.
According to the transformer design, I'm not really fully understand about winding to the margins and full width.
I also cannot open the transzip. Is it open by using LTspice?
Do you mean that for the 300uH...
