Problems solved by technology
The existing power supply for battery charging and discharging is generally placed in a combined power cabinet independent of the needle bed. DCDC power supply requires a long and thick cable to connect to the needle bed. DCDC power bus also needs to use copper plates. Connection method, this kind of power supply structure is a waste of space, low efficiency, high cost, and very inconvenient to maintain. Moreover, the existing DCDC power supply generally has low conversion efficiency, large power loss, and low utilization of the power grid. problem, so it needs to be improved

The invention provides a high-efficiency power cell formation and capacity grading integrated power supply which comprises an input bus, a transformer, an output rectification filter circuit, a DC battery output module, an ADC sampling circuit, a DSP and peripheral control circuit, a PWM circuit and an auxiliary source circuit which are integrally installed on a needle bed through four-channel hardware integration. One end of the input bus is connected with the transformer, the other end of the input bus is connected with the auxiliary source circuit, the auxiliary source circuit is connected with the DSP and peripheral control circuit, the DSP and peripheral control circuit is connected with one end of the transformer through the PWM circuit, and the other end of the transformer is connected with the output rectification filter circuit. The other end of the output rectification filter circuit is connected with a DC battery output module, and the other end of the DC battery output module is connected with a DSP and peripheral control circuit through an ADC sampling circuit. The integrated power supply can effectively reduce the power supply volume, reduce the power supply loss, and improve the utilization rate and the conversion efficiency of a power grid.
Description
technical field [0001] The invention relates to an integrated power supply, in particular to a high-efficiency power battery integrated into a component-capacitor integrated power supply. Background technique [0002] As the demand for batteries in the electric field has increased significantly year by year, battery composition and capacity, as a key process in the battery production process, have a direct impact on the quality and cost of the battery. The existing power supply for battery charging and discharging is generally placed in a combined power supply cabinet independently of the needle bed. The DCDC power supply requires a long and thick cable to connect the needle bed, and the DCDC power supply bus also needs to use a bronze medal. Connection method, this kind of power supply structure is a waste of space, low efficiency, high cost, and very inconvenient to maintain. Moreover, the existing DCDC power supply generally has low conversion efficiency, large power loss...
