Abstract
An electrical converter system includes a first electrical converter having a first switch, a second electrical converter having a second switch, the second converter being in parallel with the first electrical converter, and a controller in electrical communication with the first switch and the second switch and configured to calculate and output a first control signal for the first switch and a second control signal for the second switch, wherein output of the first and second control signals is asynchronous, wherein a frequency of at least one of the first control signal or the second control signal is variable.
Claims20
An electrical converter system comprising:
- a first electrical converter having a first switch;
- a second electrical converter having a second switch, the second converter being in parallel with the first electrical converter;
- and
- a controller in electrical communication with the first switch and the second switch and configured to:
- calculate and output a first control signal for the first switch and a second control signal for the second switch, wherein output of the first and second control signals is asynchronous;
- wherein a frequency of at least one of the first control signal or the second control signal is variable.
A method for controlling an electrical converter system, the method comprising:
- calculating and outputting a first variable-frequency control signal for a first switch of a first electrical converter;
- and
- calculating and outputting a second variable-frequency control signal for a second switch of a second electrical converter that is in parallel with the first electrical converter;
- wherein output of the first and second control signals is asynchronous.
An electrical converter system comprising:
- a plurality of electrical converters, electrically coupled in parallel with one another between an input voltage source and a load, each converter having a respective switch;
- and
- a controller in electrical communication with each of the electrical converters and configured to:
- calculate and output a respective control signal for each switch, wherein:
- a frequency of each control signal is calculated according to the load;
- a timing of at least one control signal is calculated according to a timing of at least one of the other control signals;
- and
- output of the control signals is asynchronous.
