DIY 2kVA SMPS 90V 15A HB PFC with IR2110 Mosfet Driver

SMPS HB PFC IR2110 2000Watt

Hello, this time I will build Switching Mode Power Supply (SMPS) with Half Bridge (HB) topology, with Power Factor Correction (PFC Boost Converter) controller with chip NCP1653 SMD SO-8. PWM Control Circuit using SG3525 and MOSFET driver using IC IR2110. This SMPS can produce output power up to 2200 Watt (peak) Load test at 8 Ohm. Output SMPS 90VDC Symmetrical.

Below the schematic SMPS HB PFC IR2110 2kVA

Download Schematic and Partlist at the end of this Post.

PWM Supply using 16V supply from transformer PWM Sanken B2 Input 500V output 12-19V and PWM controller using UC3845 MOSFET can be using IRFPG40 N-Channel Power Mosfet.

EMI Filter for this SMPS can be using 3.5mH 

NTC also can be using Resistor 5W  47-100Ohm

Core PFC using this ferrite core full turn 1x with copper wire 1.5mm, 
Core Diameter Outer = 47mm, Inner=24mm, Thickness=18mm

Trimpot adjustment:
1. For PWM frequency adjustment 30-130kHz
2. Duty cycle adjustment 30-40% Low Side gate adjustment
3. Overcurrent adjustment sensitivity
4. Aux DC out adjustment
Adjust Frequency SMPS

PWM Gate signal at 82kHz and Duty Cycle 38.1%

Trafo SMPS EE55
Np Working Frequency
30-40kHz = 18 turns
40-50kHz = 16 turns
50-60kHz = 15 turns
60-80kHz = 14 turns
80-100kHz = 12 turns
100-130kHz =  10 turns

Np 14 turns = Ns 6 + 6 output 90V copper wire 1:1.

If you want to make this SMPS I will share the Gerber file free version, Layout SMPS like this. OCP using a transistor.

Electronic Circuit is a good site for hobbyist also who would like to try DIY because it shared good circuits. If you have a personalized circuit requirement you may feel free to request it through the comment box or contact me.


me gusta esta fuente donde se consigue el lm2596 dc-dc buck converter


The download circuit is different than it indicates. There is a Full-bridge with transformer driver. Could you please modify or send me? Thank you very much

Itu daftar komponen file csv nya kok gak sama dengan di pcb, mana yg bener mas..?

Where I get the transformer PWM Sanken B2.

Hi here. can you plz give us more details abput the construction of the high frequesncy transformer? i am trying to build that smps but im really stuck

what software you make gerber?

Your circuit protection node does not match the one that is applied to the Board of the power supply. Do you have the right scheme? You can share the original Board file to my e mail
