Abstract

The invention discloses a centralized power supply type load driving method and system. The load driving system comprises a power adapter, a load unit and a PWM unit. The power adapter comprises an ACinput interface, a conversion control board and a DC output interface. The load unit is connected with a DC output interface of the power adapter through a power connecting line. The PWM unit comprises a first PWM module and a second PWM module, the first PWM module is connected to one end, connected with the power adapter, of the power connecting wire in parallel, and the second PWM module is connected to the other end, connected with the load unit, of the power connecting wire in parallel; the first PWM module is connected with the power adapter, and the second PWM module is connected withthe first PWM module. Through the interaction of the first PWM module and the second PWM module, the power required by the load unit currently connected to the power grid during working can be accurately calculated, and then the power adapter is controlled to output the total current of the corresponding magnitude, so that the overall power of the power grid is flexibly controlled.

Description

technical field [0001] The invention relates to the field of power supply systems, in particular to a centralized power supply load driving method and system. Background technique [0002] With the continuous development of LED plant lighting technology, various lighting methods have higher and higher requirements for driving power. In practical applications, lighting systems are often required to have higher lighting efficiency, larger and more uniform irradiated area, lower failure rate, lower cost and smarter lighting methods. In order to meet the above demands, centralized power supply is currently considered to be an effective means. [0003] A centralized power supply system refers to the drive and power supply of multiple different load units (such as LED lamps) by the same power supply. In a centralized power supply system, the usual implementation is to use an AC-DC constant voltage module as a primary driver at the front end to output a constant voltage, and then...
