Patent ID: 7285921

Claim:
An electric current balancing device comprising: a load device, an inverting circuit including a driving unit and at least one transformer coupled together for outputting an electric current to said load device, a detecting circuit coupled to said inverting circuit, said detecting circuit being provided for receiving and detecting an electric current of said load device and for stabilizing and providing a stabilized and calibrated electric current to said inverting circuit, and a balancing transformer device including a primary side and a secondary side, wherein a first end of said primary side of said balancing transformer coupled to said inverting circuit for receiving the calibrated electric current from said inverting circuit, a second end of said primary side of said balancing transformer coupled to a first end of the secondary side of said balancing transformer and a second end of said secondary side of said balancing transformer coupled to said load device for comparing an electric current of said load device with the calibrated electric current from said inverting circuit and for controlling said load device.
