Abstract
A bipolar high-voltage switching power supply system includes an input and a first output module for generating power at a first voltage and power rating. In another configuration, a second output module is combined with the first to generate power at double the power rating. The power supply is particularly suited for CT scanners and similar biomedical instrumentation.
Claims10
A bipolar high-voltage power supply system comprising:
- an input module for connection to a line voltage for generating intermediate power;
- and
- an output module for receiving said intermediate power and generating in response an output power of a predetermined nominal value P, said output module including a plurality of diodes arranged in one of a first configuration wherein said diodes generate a bipolar output of nominal voltage .+-.Vo, or a second configuration in which said diodes define a unipolar output of +Vo or -Vo;
- wherein said input module and said output module with said diodes in said first configuration define a first power supply;
- and
- wherein said first input modules and two output modules having said diodes arranged in said second configurations cooperate to define a second power supply having a different power rating than said first power supply.

A modular bipolar high-voltage power supply system comprising:
- an input module receiving an AC input and generating an intermediate output;
- a first and a second output module, each receiving said intermediate output and having a first configuration and a second configuration, wherein in said first configuration said first output module generates a bipolar output of a nominal voltage .+-.V and power rating P;
- and
- wherein in said second configuration said first output module cooperates with said second output module to form a power supply having a nominal power rating 2P, each said output modules generating a unipolar output of +V or -V.
