Part Number: UCC3895 I have a question about the UCC3895. I'm currently using the UCC3895 to drive the FETs in my AC/DC converter. The frequency is currently set to 100kHz using the internal oscillator. For future development, I tried inputting a 100kHz…
Part Number: UCC3895 Dear all,
we are currently developing a full-bridge circuit using the PWM full-bridge controller: UCC3895. The issue consists of ringing artifacts observed at the drain-source voltage of the MOSFETs.
Figure 1: Drain-source…
Part Number: UCC3895 Other Parts Discussed in Thread: UCC2895 , UCC28950 Tool/software: UCC3895/UCC2895 : Phase Shift Full Bridge
Hello,
I'm using the UCC3895 for a PSFB with high voltage ratio x30.
The frequency is arround 20kHz for the application…
Part Number: UCC3895 Tool/software: Hi. I am trying to understand the control side for a Full-Bridge converter, but it is hard to understand the phase-shift modulation to control such converter. My understanding is: I get my frequency response of the…
Part Number: UCC3895 Tool/software: Hi,
The peripheral circuit built by the customer using the UCC3895 chip and referring to the technical manual is shown in the following figure:
The customer hopes to adjust the duty cycle size through EA+20…
Part Number: UCC3895 Other Parts Discussed in Thread: UCC37324
Hi.
We are currently investigating one of our customers amplifier design that has UCC3895 full bridge driver making the +-180voltages for the AMP. The issue currently is that it is failing…
Part Number: UCC3895 Tool/software: Hello Mike O' ,
First, many thanks for your reply.
About the control mode, I think that with my application I would use voltage mode control. It's a high ratio converter (x30) and for the closed loop regulation…
Part Number: UCC3895 Other Parts Discussed in Thread: UCC2895 Tool/software: Hello,
I'm using the UCC2895 for PSFB power converter.
I'm using it in voltage mode control.
In simulation the result are suitable but in practice, no stability with…
Part Number: UCC3895 Dears:
When UCC3895 is used as the full bridge control, when the single bus AC voltage exceeds 380V, the duty cycle of OUTC OUTD output will be unbalanced and cannot be maintained at 50% duty cycle, resulting in high current peaks…
