摘要： 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.

摘要： The power output of a static DC--DC converter employing a current mode PWM controller is controlled upon the varying of the switching frequency, by detecting the sawtooth signal produced by the local oscillator generating a DC signal with an amplitude inversely proportional to the frequency. The power output is controlled by alternatively clamping the output voltage of the error amplifier of the PWM controller at a voltage proportional to the amplitude of the DC signal, or by offsetting the signal present on the current sensing resistor by a voltage corresponding to the difference between a constant voltage and the DC signal.

摘要： A control device controls a switching converter having an input alternating supply voltage and a regulated direct voltage at the output terminal. The converter comprises a switch and the control device is adapted to control the on time period and the off time period of said switch for each cycle. The control device has a first input signal representative of the current flowing through at least one element of the converter and comprises a zero crossing detector adapted to detect at least one pair of first and second zero crossings of said first signal for each switching cycle, said second zero crossing immediately following the first zero crossing and occurring in opposite direction with respect to the first zero crossing. The control device comprises a synchronizer adapted to synchronize the start of the on period with each second zero crossing of said first signal.

摘要： A control device that controls a switching circuit and minimizes hard switching that occurs in the switching circuit of a half-bridge resonant converter having a high-side transistor and a low-side transistor. The control device is configured to turn the high-side and low-side transistor on and, so that a square-wave voltage is applied to a primary winding of a transformer. The controller starts the switching of the half-bridge converter by first turning on the low-side transistor for a first time period useful for pre-charging a bootstrap capacitor couplable to the middle point of the half-bridge, and then turning the low-side transistor and the high-side transistor off for a second time period that immediately follows and is longer than the first time period.
