Efficiency of the power supply: between 92..94%. All information about the LLC Resonant SMPS project is given, transformer winding information, sprint layout pcb drawing.

Salvaging ferrite cores with Hot Air

Method: Salvaging ferrite cores Why The world is full of electronics being unceremoniously discarded. Said electronics contains power supplies. Said power supplies contain a number of magnetics, namely transformers and chokes with ferrite cores, of all sorts of sizes and shapes (well, usually E or EI, but anyway). A computer power supply will have several.

Laboratory Power Supply 10A 2X40V L6562 PFC TMS320F28062 SMPS

Smps circuit controlled by TMS320F28062 IR4427 Gate driver. Designed with pfc circuit L6562 The design of printed circuit boards and the creation of electrical schemes is realized through Eagle cad. Due to the design of the resulting device, the inlet filter is together with an active rectifier placed on a separate printed circuit board. On

600W LED Dimmer Circuit PFC ICE2PCS01 UCC28C43

This block is used to reduce and stabilize the voltage produced by the PFC block. The output voltage of this block is controlled by the control signal. Since the output voltage is higher than the safe touch (according to the CSN standard), it is possible to use the lower switch at the lowering drive. UCC28C43

IR2161 SMPS Circuit IR2153 Alternative

I’ve shared a lot of SMPS power supply projects with IR2153, especially AT, ATX power supply. The IR2153 works great for evaluating power transformers.
