Patent ID: 7808221

Claim:
A current regulation module, comprising: a linear power conversion circuit, electrically connected to an outer power supply to output a load current, wherein the linear power conversion circuit comprises at least one first switch; a switching power conversion circuit, electrically connected to the outer power supply, wherein the switching power conversion circuit comprises at least one second switch; a first current detector, used to detect the load current to output a detected current value; a controller, used to control the at least one first switch and the at least one second switch in accordance with the detected current value to make the linear power conversion circuit strengthen the dynamic response ability to the sudden change in the load current, and make the switching power conversion circuit strengthen the dynamic response ability to the sudden change in the load current; and an energy-regenerate circuit electrically connected to the switching power conversion circuit, when the at least one first switch and the at least one second switch are turned off, the energy-regenerate circuit receives the electrical energy on the switching power conversion circuit to make the value of the load current equal to zero.
