Tripp-Lite APS1012SW Inverter Inside Look, Part 1

Let’s take a closer look inside the Tripp-Lite 1000W sine wave inverter/charger.

Product information:

So a power inverter is a device that takes DC voltage and converts it to AC voltage:

In this case, I have a power inverter that takes 12 volts DC from a battery bank and produces 120 volts AC at 60 Hz. This will be a look inside the box to see how that is done.

This unit weighs in at about 35.5 lbs. (11.6 kg) and most of that weight is in the large output transformer that takes up half the internal volume.

The other half of the unit is a couple of large heat sinks with a total of 20 high current MOSFETs in the form of an H-bridge that drive that transformer. Then there is the transfer switch hardware and logic that functions a lot like a UPS and can switch from grid power to DC/battery power to supply the output. And like a UPS, there is also a built-in battery charger function.

The next video will delve into the actual workings of the device:
