Control circuit and method applied to different load voltages and robot

The invention belongs to the technical field of electronic circuits. The invention provides a control circuit and method applied to different load voltages and a robot. The control circuit comprises avoltage transformation module and a control module, a power supply signal output by a power supply module is received through the voltage transformation module, voltage transformation is conducted onthe power supply signal, and then the power supply signal obtained after voltage transformation is adjusted through the control module so that different power supply voltages can be output to independently supply power to different loads. Therefore, the control module is arranged to flexibly adjust the power supply signal after voltage conversion; the independent power supply can be carried out for different loads; a plurality of direct-current/direct-current transformers are not needed; the circuit is simple in structure, the situation that troubleshooting is difficult when a power supply system breaks down is avoide
