Bootstrap circuit in DC/DC static converters

摘要

The present invention concerns a bootstrap circuit in DC/DC static converters comprising first current generator means controlled to close in function of a first signal and a recharge circuit of a capacitor. The bootstrap circuit has the characteristic of comprising second current generator means controlled to close with a second signal synchronous with the first signal, the second signal has times and modalities such to send to the capacitor recharge currents such to compensate the discharge of the capacitor itself.
