TWO-STAGE CLOCKED ELECTRONIC EVERGY CONVERTER

摘要

A two-stage clocked electronic energy converter for transmitting an electrical power may include a first connection for connecting an electrical energy source, a second connection for connecting a load, and an intermediate circuit capacitor, wherein a first stage of the energy converter has a first converter in the boost operating mode, which first converter converts an electrical voltage at the first connection into an electrical intermediate circuit voltage at the intermediate circuit capacitor, and wherein the intermediate circuit capacitor supplies a second stage of the energy converter, which second stage supplies the load with electrical energy controllably in terms of the power, wherein a control unit sets the power drawn from the intermediate circuit capacitor by the second stage in such a way that an instantaneous minimum of the intermediate circuit voltage that is brought about by the drawing of power is greater than a predefined voltage comparison value.
