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. ThisNguồn xung SMPS can produce output power up to 2200 Watt (peak) Load test at 8 Ohm. OutputNguồn xung SMPS 90VDC Symmetrical.
Below the schematicNguồn xung 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 thisNguồn xung 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
PWM Gate signal at 82kHz and Duty Cycle 38.1%
Transformer Ferrite EE55/28/21
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
