Moreover, inverters mostly don’t carry a built in battery charger whereas all UPSs have a built in automatic battery charger with them to facilitate instant charging of the concerned battery when mains AC is present and revert the battery power in inverter mode the moment input power fails.Īlso UPSs are all designed to produce an AC having a sine waveform or at least a modified square wave resembling quite like its sine wave counterpart. However, in most cases an inverter may not be equipped with many automatic changeover functions and safety measures normally associated with an UPS.
What’s the difference between an uninterruptible power supply (UPS) and an inverter? Well, broadly speaking both are intended to perform the fundamental function of converting battery voltage to AC which may be used to operate the various electrical gadgets in the absence of our domestic AC power. It also includes a built-in universal smart battery charger. A compromised design of an UPS system presented here may well suffice the needs. Its inverter circuit utilizes a modified sine wave design.Īn uninterruptible power supply with elaborate features may not be critically required for the operation of even the sophisticated gadgets. It may be used to power not only the usual electrical appliances but also sophisticated gadgets like computers. A simple idea presented here can be built at home using most ordinary components to produce reasonable outputs.
