  • Publication number: 20250088151
    Abstract: A signal amplifier includes a driver and a network of switches forming a power converter coupled to a H-bridge circuit. The power converter has a flying capacitor and an inductor. The H-bridge circuit receives a converted voltage from the power converter and applies an output modulated voltage to a load, for instance a loudspeaker. The driver drives the network of switches in a neutral state, a first state and a second state. In the neutral state no voltage is applied to the load. In the first state, an input voltage supply and the inductor are serially coupled, and the flying capacitor is coupled in parallel with the serially coupled input voltage supply and inductor. In the second state, the flying capacitor is coupled in series with at least one of the input voltage supply and the inductor. The signal amplifier may be a multi-level class D or class H amplifier.

  • Patent number: 11990831
    Abstract: A buck-boost power converter is operable in a first mode (step-down) or in a second mode (step-up). The power converter has an inductor, a flying capacitor, a network of six switches and a driver adapted to drive the network of switches with a sequence of states. Depending on the mode of operation the sequence of states comprises at least one of a first state and a second state. In the first state the ground port is coupled to the second port via two paths, a first path comprising the flying capacitor and the inductor, and a second path comprising the flying capacitor while bypassing the inductor. In the second state the first port is coupled to the second port via a path that includes the inductor and the ground port is coupled to the first port via a path that includes the flying capacitor while bypassing the inductor.

  • Patent number: 11967901
    Abstract: A power converter which has a reservoir capacitor, a first flying capacitor, and first and second inductors coupled to a network of switches is presented. A driver is adapted to drive the network of switches with a sequence of states during a drive period. The power converter is operable in a first mode to deliver an output current using both the first and second inductors and a second mode to deliver the output current using the first inductor and without using the second inductor. When a load current is above a threshold value, the driver drives the network of switches in a first sequence of states to operate the power converter in the first mode. When the load current is equal or below the threshold value, the driver drives the network of switches in a second sequence of states to operate the power converter in the second mode.

  • Patent number: 11637491
    Abstract: A power converter includes a first conversion circuit coupled to a first port, a second conversion circuit coupled to a second port, and a driver. The first conversion circuit has a first flying-capacitor coupled to a first network of switches, and two inductors both coupled to the second conversion circuit. The second conversion circuit has a second flying-capacitor coupled to a second network of switches. The driver drives the first and the second network of switches with a sequence of states having at least one of a first phase and a second phase. When the power converter operates as a step-down converter, the first phase charges the second flying-capacitor and the second phase discharges the second flying-capacitor. When the power converter operates as a step-up converter, the first phase discharges the second flying-capacitor and the second phase charges the second flying-capacitor.
