    Not able to get high current from buck boost (sepic) converter made using TL494

    I am trying to build a buckboost converter for converting 5-40v input to 5-35V output at 3A max to use it for many purposes by usign TL494. I am using a SEPIC topology as i want a non inverting output. I simulated the circuit in proteus. The circuit works fine when i connected a 500 Ohm load, I...

    High-Current DC-DC switching regulator - Inductor Current limit

    I have been "playing around with" some DC boost switching regulator designs for use in a solar panel DC-DC converter typically 33V to 48V. Typically I use a switching frequency of about 150Khz and an inductor of around 68uH - this seems an OK compromise for switching time losses, current ripple...

    Ringing on inductor current waveform (buck converter)

    Hi guys! I'm working with the power stage for a buck converter, but when I did some measures with the scope I saw thet my inductor current waveform has a thing that I think are ringing spikes. Of course this is not a perfect triangular wave like in simulations hahaha. Background: The green...
