Abstract
An apparatus may determine a parameter related to a voltage value at a midpoint terminal of a system power device, and may adjust a voltage applied to a second terminal of the system power device based on the parameter and a reference value. The second terminal may be different from the midpoint terminal.
Claims20
An apparatus comprising:
- converter circuitry configured to convert input voltage to output voltage;
- a switch comprising a first switch terminal and a second switch terminal, wherein the first switch terminal is connected to a terminal of the converter circuitry, the switch is configured to connect between the terminal of the converter circuitry and a terminal of a system power device and to apply the output voltage from the converter circuitry to the terminal of the system power device when the switch is controlled to connect the first switch terminal to the second switch terminal;
- and
- controller circuitry configured to obtain a first parameter and to control, based on the first parameter, the switch to connect the first switch terminal to the second switch terminal or disconnect the first switch terminal from the second switch terminal, wherein the first parameter comprises a time value related to a time of day.
