Thanks JDBX,
The link you sent is quite informative.

Padmanabhan, you're welcome !
For evaluate / learning the mechanism of this kind of smps ( royer - like topology ) you can try to assemble it in simulator such as LTSpiceIV ( or TI-TINA or others ). However, should be kept in mind, that simulator is just simulator. In the real world, the 'real assembler' is solder, multimeter, scope etc. Hope this useful.

Hi All,

The circuit should be similar to the circuit in this link.

I dislike that first PCB design. No i am not exspert in SMPS yet, but the distance from primary to secondary is much much to small to be considered as safe. He do change the layout, but i still would prefer larger spacing.

Anyone know what topology used on this SMPS ? It is not a half bridge for sure.

 

[Jagd.Panther]

It's halfbridge (if you are referring to the schematic in the first post)

Thank Jagd.Pather, please notice the input capacitor is paralel (not series). I just learn about SMPS (newbie) so please correct me if i'm wrong.. Can we still categorize this to half bridge?

Sure. It's a half-bridge. You can connect DC-block cap to ground, this changes almost nothing except the cap DC voltage.
I'm attaching a pic with HB examples. What matters is "power switches" configuration

Interesting. Thanks a lot for the enlightment.
