Abstract
Systems, apparatuses, and methods are described for discharging an input voltage by utilizing discharge circuitry configured to produce a relatively constant discharge voltage value/output voltage, a relatively constant discharge current value/output current, or a relatively constant discharge power value/output power. The discharge circuitry may include at least one power device, such as a DC to DC converter.
Claims27
An apparatus comprising:
- a discharge circuit comprising:
- a first switch in a first series connection with a first resistor, and
- a second switch in a second series connection with a second resistor, wherein:
- the first switch and the first resistor are connected in parallel to the second switch and the second resistor,
- the discharge circuit is configured to discharge an input voltage of a system power device, and
- the discharge circuit is configured to discharge the input voltage in response to an indication related to discharge;
- and
- a controller configured to operate the discharge circuit to discharge the input voltage and to regulate an output voltage of the discharge circuit.
