CONTROL METHOD AND CONTROL MODULE FOR CONTROLLING AN ASYMMETRIC DC-DC CONVERTER |
摘要 |
A control method is provided for controlling an asymmetric DC-DC converter including first and second power switches that are driven respectively by first and second control signals, and a voltage-converting circuit that is operatively associated with the first and second power switches for generating an output signal. The voltage-converting circuit includes a primary coil unit and a secondary coil unit operatively associated therewith for voltage conversion, and including first and second coils that have a turn ratio not equal to one. The control method includes: sampling the output signal to obtain a sample signal corresponding thereto; and generating the first and second control signals, which correspond respectively to first and second duty cycles having a sum of one, based on a comparison between the sample signal and a reference signal such that the first and second power switches are driven in an alternating manner. |
