power converters

Hi! I have two driver boards for xenon flash light. I received them faulty, with some signs of previous repair attempts. For learning purposes I am also trying to fix... :) Some notes: I rev. engineered the circuit board and put it into ltpice (hope I did it right). Since I did not found any...

Hello Community, i want to understand the internals of this circuit which are illustrated in this graph (ignore the red curve), i would like to know how the turn off of the thyristor happens

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...

Hi! This survey is being conducted in conjunction with EETech and All About Circuits. It is a good opportunity that might benefit some of our loyal readers and forum members. If you would be willing to participate in a 90-minute virtual video meeting where we will discuss your experiences and...

Hi, We have designed a 50kW 3 level boost converter for our fuel cell EV application with liquid cooling. It is an IP65 module of dimensions 400mm x 300mm x 85mm. Its internal ambient temperature is rising very high. There is no specific component that emitting abnormal heat it seams, but we...
