Abstract
Interleaved converter and method for controlling such inverter are provided. The converter includes a plurality of phasing stages. The converter further includes a calculator configured to calculate a duty cycle value of the converter. A processor is configured to receive the calculated duty cycle value. A rulebase is coupled to the processor and includes a set of phase-selection rules configured to select a respective phase number based on the calculated duty cycle value.
Claims8
An interleaved converter comprising:
- a plurality of phasing stages;
- a calculator configured to calculate a duty cycle value of the converter;
- a processor configured to receive the calculated duty cycle value;
- and
- a rulebase coupled to the processor and including a set of phase-selection rules configured to select a respective phase number based on the calculated duty cycle value, wherein the selected phase number allows reducing the magnitude of AC ripple therein.
