Hi Jared,
Thank you for the query.
The UCC3817 and UCC3818 are second generation possible p2p replacement for the UC3854.
You can also consider the UC2854x family.
All of the parts mentioned are compatible from a pinout, package & functionality perspective…
Part Number: UC2854B Other Parts Discussed in Thread: UCC3818 , UCC28070 CURRENT ERROR AMPLIFIER
This error amplifier configuration conventionally has a resistor from the inverting input to common, and a resistor from the multiplier output to a negative…
Part Number: UCC28050 Other Parts Discussed in Thread: UCC2818 , , UCC3818 Could you tell me more about compliance with current harmonics standards BOEING DO160/F/or G section 16.7.1 and AIRBUS ABD0100.1.8.1/C section 6.2.1.4 (more constraining). In the…
Hello,
That is a strange behavior. I would not think changing the RT and CT ration would do that. The RT sets the charge current.
I do not know of any other way to synchronize the UCC3818 that is presented in the application note. It does limit the duty…
Part Number: UCC28180 Other Parts Discussed in Thread: UCC3818 , , UCC28019 Dear Team,
Here is Kevin from the Delta Taiwan team.
1. Why this PFC pre-controller doesn’t have Vin-sense and input current sense?
How does it achieve shaping input current…
Hello John,
Can you find the data sheet from TI website?
www.ti.com/.../ucc3818.pdf
Page 22,
8.2.2.5 Current Loop
GID(s)=(Vout*Rsense)/(S*Lboost*VP)
Rsense is a shunt resistor , if I use current transformer to sense current.
Do I have to modify Equation…
Other Parts Discussed in Thread: UCC3818 , UCC3817 Hello,
Can you suggest a PWM controller for a non-isolated boost converter which should work on single phase rectified ac, as well as three-phase rectified ac.
Part Number: UCC28180 Other Parts Discussed in Thread: TINA-TI , , UCC3818 Tool/software: TINA-TI or Spice Models Hi, I want to ask that how to include the UCC28180 PSPICE model in the simulation software?
First, I used the SIMETRIX to include this model…
