Abstract

See full text

A three-level flying capacitor multi-level (3L-FCM) power converter is controlled by a switching signal generator having a reference signal for generating switching signals for driving a first pair S1, S1′ and a second pair S2, S2′ of switches. Circuitry generates, from the reference signal, a first modified reference signal defined as half of the sum of 1 and the reference signal. From the first modified reference signal a second modified reference signal is generated having a half-period phase shift from the first modified reference signal. A carrier signal having a constant frequency is generated and a first comparator and a second comparator compare the first and the second modified reference signals to the carrier signal to generate frequency signals for driving the first pair of switches S1, S1′, and the second pair of switches S2, S2′, respectively.
