Applied Mechanics And Mechanical Engineering. Could you let us know where do you get this schematic?
This thread has been locked. If you have a related question, please click the ” Ask a related question ” button in the ucd28019 right corner. Is there any explanation for this? Aug 4, 2: When I replace the switching transistor model with a power mosfet model, it udc28019 becoming a PFC!!! If I can’t solve this, I will be consigned to think that it’s a simulation issue and just go on with constructing the circuit. I decided to retain the switching transistor model that T. But the waveform that resulted is basically the same as the one i posted above.
[SOLVED] PFC Simulation (UCC)
R8 and INA maybe for another function. SPI verilog testbench code 6. If you have further questions related to this thread, you may click “Ask a related question” below. Meanwhile hundreds of amps of current are being drawn from the input.
The original schematic was designed for W, I think. All content and materials on this site are provided “as is”. 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.
Circuit suggestion for an current limited power supply application 6. Power factor correction PFC is an effective method to reduce harmonic current in power grid. Also wondering where the schematic section is from? Let me know if this helps. 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.
Part and Inventory Search. The model has been tested for the W EVM application only. Ask a related question What is a related question?

However, if I reduce R23 from 30m to 20m then the distottion goes away. ALSO, I will attach my sort of new schematic with the waveforms. Note that the circuits in the datasheet all have input filters circled in red below. The rectifier uses DC voltage outer loop control method and the input current inner loop control method, three-phase inverter output current uses SPWM modulation. Mentions Tags More Cancel. Aug 7, 6: Where is that current going? Looking at your graphs, there’s two main problems: 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.
Anyway, thanks for really trying to help godfreyl. Use of the information on this site may require a license from a third party, or a license from TI.

Your circuit isn’t doing any of those.
Cadence Virtuoso run different version called version 2. It would be useful to look at the gate voltage and the voltage on the right of the inductor to see what’s going on with the switching. By the way, I’m using the OrCad
