A Non-Isolated Bidirectional Buck-Boost Chopper With Auxiliary Converter for Battery Energy Storage …

The proposed chopper is controlled such that the capacitors of the auxiliary converter store and release most of the converter energy instead of relying solely on a bulky and heavy inductor. As a result, the proposed chopper is lighter and smaller than the conventional four-switch non-inverting buck-boost converter.

Uninterruptible power supply

Uninterruptible power supply. An uninterruptible power supply ( UPS) or uninterruptible power source is a type of continual power system that provides automated backup electric power to a load when the input power source or mains power fails. A UPS differs from a traditional auxiliary / emergency power system or standby generator in that it ...

Emergency power system

An emergency power system is an independent source of electrical power that supports important electrical systems on loss of normal power supply. A standby power system may include a standby generator, batteries and other apparatus. Emergency power systems are installed to protect life and property from the consequences of loss of primary ...

Auxiliary power

Auxiliary power is electric power that is provided by an alternate source and that serves as backup for the primary power source at the station main bus or prescribed sub-bus. An offline unit provides electrical isolation between the primary power source and the critical technical load whereas an online unit does not.
