CONTROLLER FOR DETECTING AN OUTPUT CURRENT OF A POWER CONVERTER, DEVICE FOR DETECTING AN AVERAGE OUTPUT CURRENT OF A POWER CONVERTER, METHOD FOR DETECTING AN AVERAGE OUTPUT CURRENT OF A POWER CONVERTER, AND METHOD FOR DETECTING AN OUTPUT CURRENT OF A POWER CONVERTER
CONTROLLER FOR DETECTING AN OUTPUT CURRENT OF A POWER CONVERTER, DEVICE FOR DETECTING AN AVERAGE OUTPUT CURRENT OF A POWER CONVERTER, METHOD FOR DETECTING AN AVERAGE OUTPUT CURRENT OF A POWER CONVERTER, AND METHOD FOR DETECTING AN OUTPUT CURRENT OF A POWER CONVERTER
A device for detecting an average output current of a power converter includes a current generation unit, a first voltage generation unit, a first current mirror unit, and a second current mirror unit. The current generation unit generates a first charge current according to an intermediate voltage. The first voltage generation unit generates a first node voltage according to the first charge current, a first discharge current, a turning-on time, and an inverse turning-on time. The first current mirror unit generates a first current according to the first node voltage, and generates a second voltage corresponding to the average output current of a secondary side of the power converter according to the first current. The second current mirror unit generates the first discharge current according to the first current.
