Abstract
A converter device includes a converter and a controller to operate the converter. The converter includes reactive components which include a flying capacitor. To perform at least two different operation modes, the converter further includes seven switches. A mode selection logic of the controller selects one of the operation modes depending on desired operating conditions. The converter device is highly flexible and enables a high power processing efficiency over the full operating range by properly selecting a suitable operation mode.
Claims15
A converter device for converting an input voltage into an output voltage, the converter device comprising:
- a converter comprising a first input voltage terminal and a second input voltage terminal to apply the input voltage, a first output voltage terminal and a second output voltage terminal to provide the output voltage to a load and reactive components;
- a controller to operate the converter, the converter comprising seven switches to perform at least two different operation modes, the reactive components comprising a flying capacitor, the controller comprising a mode selection logic to select one of the at least two operation modes depending on desired operating conditions.
A method to operate a converter device, the method comprising the following steps:
- providing a converter device for converting an input voltage into an output voltage, the converter device comprising a converter comprising a first input voltage terminal and a second input voltage terminal to apply the input voltage, a first output voltage terminal and a second output voltage terminal to provide the output voltage to a load and reactive components, the converter device further comprising a controller to operate the converter, the converter comprising seven switches to perform at least two different operation modes, the reactive components comprising a flying capacitor, the controller comprising a mode selection logic to select one of the at least two operation modes depending on desired operating conditions;
- selecting one of the at least two operation modes via the mode selection logic depending on the desired operating conditions;
- and
- operating the switches of the converter to perform a selected operation mode.
