there is a possibility to increase the output voltage by 10% for a smps with KA3525 when the duty cycle is 49% and I can not change the ratio in the transformer?
I wrapped the smps switching transformer with a copper tape to reduce the emi. What would you suggest the grounding procedure.
The tape should be Grounded to DC directly or
it should be grounded...
I would like to do some LOAD test for 12V, 24V and 48 Volt SMPS. Is there any Schematic available to build a MOSFET based Adjustable DC LOAD
OK................... How much it will cost ? (Stereo - Two assembled PCBs)
Just one thing puzzles me. 1) current for 350w at 100 volts is 3.5 amps 2) The maximum current for AWG 22 (0.6mm) is 0.92 amps. Max frequency is 42
I really like the simplicity of the design. Could you supply some diagramms for load responses. Maybe a LTSpice - file that would be really cool. Thanks
This topic is not about flayback trafos since with pushpull technic we donīt store energy in the core (gap actually).
Really....................They are so cool
I just love it.!!!!!!!!!!!!!!!!!!!!
help...sir please shared sofware/formula transformer calculation for smps plyback inverter....
soory bad my english....
help...sir please shared flyback transformer turn ratio calculation...
sory bad my english
I bought (T45-26-15 PC40) from aliexpress
but I didnt compliet the circuit yet
Can you post your actual schematic?
I am seeing the MOSFET take a very long time to switch, about 1.5 usec
I would guess problems
This article will illustrate a simple procedure to devise an unregulated switching symmetric power supply of 350W.
This unit can be substituted
