[0-30 Vdc Stabilized Power Supply]

Thanks audioguru, I've added a capacitor (10000uF, 63V) in parallel with flyback, C7 no longer explodes (and even does not warms up).  8)

[0-30 Vdc Stabilized Power Supply]

Hi all! Can anyone help me?

I've built this power supply. All worked fine. But when I try to load it (15-20 V, 1.5-2 A), C7 explodes. The load itself is a flyback (its primary winding, 5 turns of 1mm wire), which is driven by a power MOSFET. Could this be because of self-induction impulses?
