Operational amplifier-based load current equalization circuit

The invention relates to an operational amplifier-based load current equalization circuit. A current amplification circuit A1 is used for acquiring a single-module output current and converting the current to a voltage signal, an output voltage signal is transmitted to a voltage following circuit A3 and is accessed to a current equalization bus CS-BUS end and a + input end of a current error adjustment circuit A4, a bias voltage generated by a bias voltage circuit A2 is simultaneously accessed to a - input end of the current error adjustment circuit A4, and an output voltage signal end of thecurrent error adjustment circuit A4 is connected to a voltage error amplification circuit A5. By the operational amplifier-based load current equalization circuit, the defect that a working point of an internal circuit cannot be adjusted by a peripheral circuit in the prior art (an integrated circuit scheme) can be overcome, optimal configuration of an electrical parameter can be achieved in special application occasion,
