dc - dc converter resonant transition and control method dellatransizione resonant dc - dc converter

摘要

The energy source is connected to the primary of a transformer (22) whose secondary is connected to the output terminals via a diode (14) and capacitor (16) network. A control transistor (28) in series with the primary winding receives a logic control signal to close. A capacitor (30) is connected in parallel with the control transistor. The transistor is controlled by a control circuit (36). A voltage comparator (32) connected in parallel with the capacitor generates logic level signal which is supplied to the control circuit.
