PROBLEM TO BE SOLVED: To provide a method of magnetization balancing for a switching power supply having at least two MOSFETs.SOLUTION: The method includes: measuring first and second commutation times for first and second MOSFETs, respectively (step 602); adjusting the timing of the on time (pulse width) of the first MOSFET's gate 1 relative to the on time (pulse width) of the second MOSFET's gate 2 (step 604); and determining whether the first and second commutation times are equal (step 606).SELECTED DRAWING: Figure 6 |
