Part Number: TIDA-00443 Hi,
In section 4.2.4, the VF_bridge per element is taken as 0.85 V for loss calculation. Could you please let me know from where this information is obtained. In the datasheet of GBJ1508, it is only mentioned that VF_bridge per…
Part Number: TIDA-00443 Other Parts Discussed in Thread: TIDA-01503 , Can I use TIDA-01503 board bias power to the TIDA-00443 ?
Is there any other better suggestion?
Part Number: TIDA-00443 In section 4.2.6, the switching frequency used is 98 kHz instead of 100 kHz. What’s the reason for this.
If we look at the schematic, it is found that two 0.68 uF caps are used. Could you please let me know why two caps are…
Part Number: TIDA-00443 Hi,
In section 4.2.8, how the second part of the power loss (0.5*fsw*Vout*Qrr) is derived.
I understand it is due to Qrr, how exactly is the equation derived. Could you please explain.
Thanks and regards,
Part Number: TIDA-00443
Referring to section 4.2.6in the design document, I can find that the Iripple = 2.75A.
I calculated the RMS current as shown below:
The data sheet of the selected capacitor shows that at 100kHz, it can carry an RMS current close…
Other Parts Discussed in Thread: TIDA-00443 Tool/software: Hi guys,
I used UCC28180D and gate driver UCC27517ADBVR to design a PFC and output is 390V following the design reference 900W TIDA-00443 for our 230V motor drive project. The load is BLDC pump…
Part Number: TIDA-00443 Dear TI Experts,
I was referring TIDA-00443 Reference design from TI. TI used three 220uF capacitor C4,C5 and C18 at the output of PFC. What is the total power dissipation in these capacitor?.
TI calculated the ripple current as…
Part Number: TIDA-00443 Other Parts Discussed in Thread: UCC28180 Hi,
This is kalyan. we are currently working on the TIDA00443 PFC circuit for charger application.
In fixed boost mode we are facing some issues related to input AC current,
for the given…
