Portable DC UPS for Wi-Fi Routers During Power Cuts

Power Electronics / ConsumerEasy-Medium

Approx. component budget: Rs. 2,500 - 5,000

Objective

Keep a router running for hours during outages and measure the backup time and switchover speed.

A battery-backed power unit that boosts a 12 V battery to the router's 9 V or 12 V input and switches over with no break when power fails.

Power path control, ideal-diode switching and battery sizing.

Li-ion pack with protection board, boost converter, ideal-diode ORing, multimeter, scope. Use a protected cell holder and fuse.

Built and tested Portable DC UPS for Wi-Fi Routers During Power Cuts; objective: keep a router running for hours during outages and measure the backup time and switchover speed.
Measured and analysed switchover time in milliseconds and backup time at the router load; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
