Realization in Grid-connected Discharge Device of Lithium Power Battery Based on DSP

In order to overcome the large amounts of energy waste in the process of lithium battery discharge,this pa-per designs a digital grid-connected discharge device of lithium battery.The device with a core of TMS320F28035 re-alizes the sine inverter of unit power factor,employing the dual-loop one cycle control algorithm which uses feedback plus feed-forward,and also makes full use of the CLA,high-precision PWM and A/D modules of DSP controller,which greatly simplifies the hardware circuit.In general,the system is simple,flexible and powerful,realizing the ener-gy-saving and precisiong braking.
