Abstract
A power supply comprises at least one input to couple the power supply to a power source. The power supply also comprises at least one switched-mode power circuit configured to extract electrical energy from the power source, the electrical energy to be transferred to a load. The power supply additionally comprises at least one control module coupled between the at least one input and the at least one switched-mode power circuit. The control module is configured to control operation of the switched-mode power circuit to regulate a voltage-to-current ratio at the at least one input of the power supply.
Claims20
A power supply, comprising:
- at least one input to couple the power supply to a power source;
- at least one switched-mode power circuit configured to extract electrical energy from the power source, wherein the electrical energy is to be transferred to a load;
- and
- at least one control module coupled between the at least one input and the at least one switched-mode power circuit, the control module configured to control operation of the switched-mode power circuit to regulate a voltage-to-current ratio at the at least one input of the power supply.
A power supply, comprising:
- a respective input to couple the power supply to each of three phase outputs of a three-phase power source;
- a respective switched-mode power circuit configured to extract electrical energy from a corresponding phase of the power source;
- and
- one or more control modules coupled between the respective power source inputs and the respective switched-mode power circuits, the one or more control modules configured to control operation of the respective switched-mode power circuits to regulate a voltage-to-current ratio at each of the respective inputs of the power supply.
A method of regulating a power supply having an input to couple the power supply to a power source and a switched-mode power circuit to extract electrical energy from the power source, wherein the electrical energy is to be provided to a load, the method comprising:
- obtaining a first signal indicative of a voltage wave shape at the input of the power supply;
- obtaining a second signal indicative of a current wave shape at the input of the power supply;
- comparing the first signal and the second signal to detect a difference between the first signal and the second signal;
- and
- controlling, based on the detected difference between the first signal and the second signal, operation of the switched-mode power circuit to regulate a voltage-to-current ratio at the input of the power supply.
