US Patent 7880458 Method and device for driving power converters

A device and method for driving a converter circuit that supplies a charge via a first electronic switch and a second electronic switch alternately turned on and off. A generator module generates a memory signal, indicating the duration of a first dead-time interval. A delay module, sensitive to the memory signal controls turning-on of the first electronic switch with a delay, with respect to turning-off of the second electronic switch, so that a second dead-time interval has a duration substantially equal to the duration of the first dead-time interval.
