A topology of bi-directional multi-output multi-function converter is designed in a BBU. The concept of bi-directional multi-function multi-output converter may be designed for the application of BBUs in a data center to provide multiple control functionalizes, such as battery discharging, battery charging, fan speed control, pump control, as well as providing power for multiple components/devices simultaneously. The proposed converter has two characteristics: bi-direction and multi-output. With the function of bi-direction, the battery discharging and charging can be accomplished with the same converter. With the function of multi-output, different rails of output voltages or power can be applied to different components or devices in BBU, such as fan, pump, control IC chip, sensors and etc. With the proposed concept of bi-directional multi-function multi-output converter, only one converter is required to achieve multiple control functions and provide power to different components, which reduces the volume and cost of a battery backup unit.
