Dynamic drive of switching transistor of switching power converter

A switching power converter comprising:

• a transformer coupled between a power source and a load;
• a switch coupled to the transformer for coupling or decoupling the load to or from the power source through the transformer;
• and
• a pulse generator generating an output drive signal for controlling on-times and off-times of the switch during a plurality of switching cycles, the output drive signal being at a first logic state during a first part of a switching cycle of the plurality of switch cycles and a second logic state during a second part of the switching cycle;
• and
• a dynamic switch drive module receiving the output drive signal and generating a switch drive signal for driving the switch based upon the output drive signal, a current magnitude or a voltage magnitude of the switch drive signal being adjusted within the switching cycle based upon an input voltage to the switching power converter and the load, wherein the dynamic switch drive module adjusts the current magnitude or the voltage magnitude from a first level to a second level and from the second level to a third level during the first part of the switching cycle, wherein the third level is less than the second level and greater than the first level.
