Abstract
A polarity-selectable high voltage direct current power supply including a first drive assembly that transforms a first low voltage DC input into a first medium voltage alternating current output; a first HV output assembly that transforms the first LV AC output into a first HV DC output, wherein the first HV output assembly defines a first input stage; a polarity selector coupled between the second output junction of the first drive assembly and the first and second input stages of the first HV output assembly, the polarity selector operable between a first configuration and a second configuration; wherein in the first configuration the first HV DC output has a positive polarity; and wherein in the second configuration the first HV DC output has a negative polarity.
Claims20
An output-polarity-selectable power supply comprising:
- a first drive assembly that receives a first voltage and outputs a second voltage, wherein the first drive assembly defines a first output junction pair;
- a first output assembly that receives the second voltage and outputs a third voltage, wherein the first output assembly defines a first input stage electrically connectable to the first output junction pair, a second input stage electrically connectable to the first output junction pair, and a second output junction pair;
- a polarity selector coupled between the first output junction pair and the first and second input stages of the first output assembly, the polarity selector comprising a set of switches operable between a first configuration and a second configuration;
- wherein in the first configuration:
- the set of switches directly electrically connects the first output junction pair to the first input stage and electrically isolates the first output junction pair from the second input stage, and the second output junction pair defines a positive polarity;
- and
- wherein in the second configuration:
- the set of switches directly electrically connects the first output junction pair to the second input stage and electrically isolates the first output junction pair from the first input stage, and the second output junction pair defines a negative polarity.
