Abstract
This disclosure describes systems, methods, and apparatuses for a power supply, the power supply configured for monitoring a voltage at an output end of the power supply; controlling, based on the voltage exceeding a first threshold, a first switch to connect a plurality of secondary windings of the power supply in series; and controlling, based on the voltage exceeding a second threshold, at least one other switch to switch in at least one capacitor into the power supply, wherein the second threshold is greater than the first threshold.
Claims20
A method of operating a power supply comprising:
- monitoring a voltage at an output end of the power supply;
- controlling, based on the voltage exceeding a first threshold, a first switch to connect a plurality of secondary windings of the power supply in series;
- and
- controlling, based on the voltage exceeding a second threshold, at least one other switch to switch in at least one capacitor into the power supply, wherein the second threshold is greater than the first threshold.
A power supply comprising:
- a transformer circuit connected between an input end and an output end of the power supply, wherein the transformer circuit comprises:
- a primary winding;
- a plurality of secondary windings, including at least a first secondary winding and a second secondary winding;
- a first switch;
- at least one other switch, each of the at least one other switch connected in series with a capacitor;
- and
- a monitoring circuit, wherein the monitoring circuit is configured to:
- monitor a voltage at an output end of the power supply;
- control, based on the voltage exceeding a first threshold, the first switch to connect at least the first and the second secondary windings in series;
- and
- control, based on the voltage exceeding a second threshold, the at least one other switch to switch in a respective capacitor into the power supply, wherein the second threshold is greater than the first threshold.
A non-transitory computer readable storage medium storing processor readable instructions that, when executed by a processor, cause the processor to perform a method for operating a power supply, the method comprising:
- monitoring a voltage at an output end of the power supply;
- controlling, based on the voltage exceeding a first threshold, a first switch to connect a plurality of secondary windings of the power supply in series;
- and
- controlling, based on the voltage exceeding a second threshold, at least one other switch to switch in at least one capacitor into the power supply, wherein the second threshold is greater than the first threshold.
