UCC28019 Model Simulation

However, if I reduce R23 from 30m to 20m then the distottion goes away. Looking at your graphs, there’s two main problems: I asked TI directly in their forum about the whole thing and this is their answer: If you have further questions related to this thread, you may click “Ask a related question” below.

Trademarks Privacy Policy Terms of Use. In this model, all the switching nodes have been removed and replaced with the average waveform at that node.

TI is a global semiconductor design and manufacturing company. In reply to LeonardEllis: We ycc28019 glad that we were able to resolve this issue, and will now proceed to close this thread.

If you have kcc28019 related question, please click the ” Ask a related question ” button in the top right corner. Since both the input boost supply and the output supply can be controlled independently, a fast transient response can be maintained at both the input for active current wave shaping and at the output for good output regulation.

A Single Phase High Power Factor Rectifier with UCC

Getting back to the first few hundred mS, what is going on there? A few points about the model: Startup has not been modeled in this Average Model, so please ignore the first ms – 1sec of the waveform as that time is required to reach the steady state.

And this is the schematic from the datasheet: Mathematical formula of the minimum separations required between two patch antennas?

Parallel operation generates loop current; one of the effective methods of suppressing the loop current is to connect limiting inductance in the inverter AC side. Its sections such as current loop and over-current protection, voltage loop and over-voltage protection, and so on, are analyzed and designed respectively in detail.


Here’s the one without: Do ucc28091 have another question? The output voltage jumps up almost instantly to about V, far above what it should be, then just sits there for mS without even any ripple.

Ucc2019 and final energy stored in a capacitor In reply to Danel October Beriong: When the ac source is in an outage condition, the proposed converter functions as a dc-to-dc buck-boost converter; therefore, the desired dc output voltage can be provided.

Also wondering where the schematic section is from? No license, either express or implied, by estoppel or otherwise, is granted by TI. When I ram your 2.

[SOLVED] PFC Simulation (UCC)

The red line is the line current, the blue line is the inductor current, and the light blue line is the output voltage supposedly.

When I replace the switching transistor model with a power mosfet model, it stops becoming a PFC!!! Secondly, after the first few hundred mS, when the circuit has settled down, the current draw at the input is horribly unsymmetrical, with a totally wrong waveform. The newly created ucc288019 will be automatically linked to this question.
