Abstract
The utility model discloses a novel continuous power supply system which mainly comprises a super capacitance energy storage unit, a compressed air power unit and a monitoring and controlling unit. When the commercial power supplies power normally, the electric power is stored in the super capacitor and the compressed air power unit.

When the commercial power backs again, the energy storage process is performed through electric power of the electrical network, The compressed air in an air tank is supplemented through a compressor. The novel continuous power supply system employs a super capacitor and a compressed air power unit, and is rapid in response, long in service lifetime, low in maintenance cost and high in adaptive capacity. The novel continuous power supply system is low-carbon and environmental friendly.
