    摘要： A DC-to-DC converter includes an input voltage node, an inductor, and a switch coupled to the inductor and the input voltage node. More specifically, the switch has an on state and off state, wherein during the on state, current flowing through the inductor increases and the off state results in a decrease of the current flowing through the inductor via a driver coupled to the switch. The driver comprises a plurality of transistors and an adaptive voltage node, wherein a voltage level at the adaptive voltage node is to vary in accordance with the current flowing through the inductor so as to decrease a variation of the amount of time to turn off the switch.

    摘要： A method for regulating a power converter includes initiating a transition of a switch coupled to an input side of the power converter from an OFF to an ON state to regulate a transfer of energy from the input to an output side of the power converter after a switch control signal generator receives an enable signal and if a feedback signal representative of an output of the power converter indicates a change in an output of the power converter. The enable signal is generated to communicate a control signal from the output to the input side in response to a first signal representative of a voltage on an output terminal that oscillates in response to an ending of the transfer of energy. The transition of the switch from the OFF to the ON state occurs substantially at a time that the first signal reaches an extremum.

    摘要： A system for converting power comprising a plurality of modules comprising a storage device, connected in series and having each at least one DC power source. A voltage control circuitry in each module connects the storage device between a maximum and minimum module voltage to create a stepwise approximation of a mains signal. A compensator unit is provided in series with the modules including a storage device charged by the power sources. A control unit is used to ramp up or down the voltage between the input and output of the compensator unit to follow the desired AC signal. When the control unit operates a module to vary the supplied voltage from either zero to the maximum or minimum values, or vice versa, the control unit applies via compensator voltage control circuitry a corresponding but opposed change in the voltage supplied by the compensator unit.
