Title: TDK LAMBDA VEGA 650W modular powersupply, fixed primary pwm, teardown
Post by: oz2cpu on May 26, 2022, 10:42:18 am
I just released two videos about this type of powersupply

TDK LAMBDA ALPHA 1000W modular powersupply

Both designs use the same topology, and same style sec sides
the sec side modules are not interchangeable between those two models

The switchmode know-how dudes of this forum
might find a few things interesting in the videos,
specially the fixed pwm primary common to all sec modules
and the sec module end regulation is done very smart,
