It looks like there’s no schematic or parts placed yet in your “UPS for various dc voltages” project, so I don’t have the circuit details to analyze. To give you a full technical analysis I’ll need at least:
• The schematic (or a net-list) showing the charger controller IC, power stage topology, battery connections, DC/DC converters, etc.
• Key component references/values (e.g. MOSFETs, inductors, diodes, feedback resistors, decoupling caps, sense resistors).
Could you please share the charger controller IC and power-stage topology you’re using, or upload the schematic file/net-list?

@copilot add 220 AC voltage source

To represent a 220V AC voltage source in your UPS project within Flux, you would add it as a key component for simulating the input power supply. Since Flux is used for designing electronic schematics and PCB layouts, adding a symbol for a 220V AC source helps visualize the power input for your UPS.
For the 220V AC source, typically, you would look for a symbol in the Flux library that represents an AC voltage source. This symbol is often depicted as a circle with a sine wave inside it or simply with the letters "AC" inside.
Here's a step to add the 220V AC voltage source to your schematic:
  1. In the Flux component library, search for an "AC Voltage Source" symbol.
  2. Once found, drag and drop the symbol onto your schematic canvas.
  3. Label it appropriately, for example, "VAC1: 220V AC", to indicate it's a 220-volt input. This name helps identify the component's role in the circuit clearly.
Remember to consider the position of this AC voltage source in your overall UPS design. Typically, it would be connected to the input stage of the AC to DC converter or rectifier circuit, which then charges the 12V battery. If you'll proceed with designing the rectifier or charger circuit next, let me know so we can outline the necessary components and their connections!

@copilot i am not able to drag and drop components

It sounds like you might be encountering a technical issue with Flux that prevents you from dragging and dropping components. Here are a few general troubleshooting steps you can try to resolve this problem. If these don't work, it might be worth reaching out to Flux's support team directly for more specific assistance.
Troubleshooting Steps
  1. Refresh Your Browser: Sometimes, simply refreshing the browser can fix minor glitches or issues with web-based applications like Flux.
  2. Check for Browser Updates: Ensure your web browser is up to date. An outdated browser might not be fully compatible with the latest version of Flux.
  3. Clear Browser Cache and Cookies: Clearing your browser’s cache and cookies can often solve loading or functionality issues.
  4. Disable Browser Extensions: Sometimes, browser extensions can interfere with web applications. Try disabling extensions, especially those that manipulate web content or are ad blockers.
  5. Use a Different Browser: If the issue persists, try using a different web browser. Flux is designed to work on modern browsers, but switching might help identify if the problem is browser-specific.
  6. Check for Flux Updates or Maintenance: Occasionally, Flux might be undergoing updates or maintenance. Look for any announcements on the Flux website or social media channels regarding this.
  7. Enable JavaScript: Ensure that JavaScript is enabled in your browser settings, as Flux heavily relies on JavaScript for interactive functionalities.
Moving Forward with the Project
Since you're dealing with a specific technical issue that prevents adding components via drag-and-drop, you might also consider sketching out your circuit design on paper or using another program temporarily to keep your project moving. You can transfer your design to Flux once the issue is resolved.
To design the charging circuit for the 12V battery from a 220V AC supply without dragging and dropping, you'd typically think about including components like:
  • A transformer to step down the voltage.
  • A rectifier to convert AC to DC.
  • A filter capacitor to smooth out the ripples in the DC output.
  • A voltage regulator to maintain a steady 12V output.
If the problem persists and you need more specific help with the circuit design or using Flux, feel free to ask for further assistance.

@copilot, how can i add a drawing?
1y

copilot

Adding a drawing or schematic to your project in Flux involves creating a new schematic file or editing an existing one within the Flux.io environment. Since Flux is a web-based electronics CAD program, you'll be working directly from your browser. Here's a general overview of how you can start adding drawings or schematics:
Step 1: Create or Open a Project
  • Create a New Project: If you haven't already, create a new project in Flux by selecting the option to create a new project or file from the dashboard or the file menu.
  • Open an Existing Project: If you're adding to an existing project, open it from your project list/dashboard.
Step 2: Access the Schematic Editor
  • Once you have your project open, look for an option to add or edit schematics. This could be labeled something like "Schematic Editor," "Add Schematic," or simply "Schematic."
Step 3: Start Drawing
  • Manual Drawing: Flux should offer basic drawing tools such as lines, arcs, and shapes, allowing you to manually draw parts of your circuit if necessary.
  • Adding Components: For electronic components, search the component library. There should be an option to add components, which you can then place on your schematic. Since you mentioned difficulties with drag-and-drop functionality, make sure that any issues there are resolved. If manual selection and placement are possible, use those methods.
  • Wiring Components: Use the wiring tool or similar functionality to draw connections between the pins of your components. This creates the electrical connections within your schematic.
Step 4: Label and Document
  • Don’t forget to label your components and connections clearly. Adding notes or labels can significantly help with understanding the circuit later or if someone else needs to review it.
Step 5: Save Your Work
  • Regularly save your progress to avoid losing any work due to unexpected issues.
If Flux supports importing schematic drawings or symbols from other CAD programs, you might also have the option to prepare parts of your drawing in another application and import it into Flux. However, this depends on the specific capabilities and file compatibility of the Flux platform.
In case you're facing technical issues or limitations with the Flux interface (such as the previously mentioned drag-and-drop issue), I recommend checking the Flux help resources or contacting their support for more assistance. They might offer specific advice or workarounds for adding complex drawings or making the most of their toolset.
