Part Number: UC3846 Tool/software: This time, during the production of WSM-400T, there was a problem of the large current being too small. The technical requirement was 400A, but the actual output was only 392A. Out of 500 units produced, 200 units were…
Part Number: UC3846 Tool/software: Hi expert,
My customer (Uni-trend) is evaluating UC3846 and they want to use Automatic Symmetry Correction in Push-Pull Configuration but don't know how to configure, could you provide some guideline about it? Thanks…
Part Number: UC3846 Tool/software:
This is an old project that has been around since 27 years ago without any design changes. During the production of WSM-400T this time, there was a problem of the large current being too small. The technical requirement…
Part Number: UC3846 Tool/software: Hi,
Measuring the parameters you mentioned, I have another question. In the following image, the signals you mentioned in the previous message are shown. In this image, the control is working correctly and we have…
Part Number: UC3846 Other Parts Discussed in Thread: UC1846 Tool/software: 1. In the Pspice for Ti software downloaded from Ti website, why is the component selection function blank? 2. There is also the Modeling Application function that cannot be used…
Part Number: UC3846 Other Parts Discussed in Thread: TL431 Tool/software: Hello,
I am using the UC3846DW controller to manage a push-pull converter. The input of the push-pull varies between 18 and 30V, and the output is regulated to 100V. With the…
Part Number: UC3846 Tool/software: A strange problem occurred on a product. The purple is the DS waveform of the power transistor, and the green is the primary current waveform of the transformer. It is normal under medium and small loads, but when the…
Part Number: UC3846 As the title suggests, using UC3846 as an H-bridge hard switch, PWM signal drives 4 MOS with a power of 20kw.
The problem is as follows:
1. Is the A and B PWM output of UC3846 complementary to pin11 and pin14? If complementary…
Part Number: UC3846 Hello,
We are working with a push-pull converter using the UC3846 chip. According to the datasheet, it mentions the possibility of controlling the converter in voltage control mode (see attached image). However, we couldn't find…
Part Number: UC3846 Tool/software: Hi there, so I've been using the UC3846 in my half bridge flyback converter design. I've been simulating it in LTSpice however I have had some trouble with the model. I'm trying to run the chip with a switching frequency…
