Multi-input channel electric energy feedback type electronic load based on bus framework

The utility model relates to a multi-input channel electric energy feedback type electronic load based on a bus framework, comprising a plurality of DC/DC modules and a MCU (Microprogrammed Control Unit) bus control loop for controlling each DC/DC module, wherein the MCU bus control loop and the DC/DC modules are respectively positioned on different PCBs (Printed Circuit Boards), the DC/DC modules are provided with direct-current input ends, direct-current output ends and control input ends, the control input ends of the DC/DC modules are connected with the control output end of the MCU bus control loop through buses, and the direct-current output ends of the DC/DC modules are connected to the same set of direct-current buses in parallel so that electric energy is reutilized. The electronic load also comprises an upper computer on which a communication interface capable of communicating with the MCU bus control loop is arranged. The multi-input channel electric energy feedback type electronic load has the advantages of multi-channel input, strong expansibility, channel modularization, convenient use and maintenance and the like, and can be mainly used for detecting direct-current power supplies.
