Abstract
An apparatus such as a power supply or other suitable entity includes a controller. The controller receives a target ripple current value indicative of a ripple current associated with an output voltage and corresponding output current of a power converter powering a load. The controller selects a switching frequency of operating the power converter as a function of a magnitude of the received target ripple current value. The controller applies the selected switching frequency to switches in the power converter to produce the output current with a magnitude of the ripple current as indicated by the target ripple current value.
Claims27
An apparatus comprising:
- a controller operative to:
- receive a target ripple current value indicative of a ripple current associated with an output current of a power converter powering a load;
- select a switching frequency of operating the power converter as a function of a magnitude of the received target ripple current value;
- and
- apply the selected switching frequency to switches in the power converter to produce the output current with a magnitude of ripple current as indicated by the target ripple current value.
A method comprising:
- receiving a target ripple current value indicative of a ripple current associated with an output current of a power converter powering a load;
- select a switching frequency of operating the power converter as a function of a magnitude of the received target ripple current value;
- and
- apply the selected switching frequency to switches in the power converter to produce the output current with the ripple current as indicated by the target ripple current value.
Computer-readable storage hardware having instructions stored thereon, the instructions, when carried out by computer processor hardware, cause the computer processor hardware to:
- receive a target ripple current value indicative of a ripple current associated with an output current of a power converter powering a load;
- select a switching frequency of operating the power converter as a function of a magnitude of the received target ripple current value;
- and
- apply the selected switching frequency to switches in the power converter to produce the output current with the ripple current as indicated by the target ripple current value.
