Abstract
A high voltage power supply can be compact with shielded electronic components. The power supply can include multiple stages separated by circuit boards. Electronic components for each stage can be directly soldered to adjacent circuit boards. Traces can pass through and electrically couple electronic components on each side of the circuit board between them.
Claims20
An x-ray source comprising:
- an x-ray tube electrically-coupled to a power supply;
- the power supply includes multiple stages, in a stack, configured to multiply an input voltage to provide a larger output bias voltage;
- each stage (a) includes electronic components on a top-side of a circuit board, (b) has an input and an output, and (c) is configured to increase voltage from the input to the output;
- the circuit board for each stage is separate from the circuit boards of other stages in the stack;
- the output of each stage, except for a highest-voltage-stage, is electrically coupled to the input of a higher voltage stage;
- the input of each stage, except for a lowest-voltage-stage, is electrically coupled to the output of a lower voltage stage;
- in each stage the electronic components are directly soldered to the top-side of the circuit board for that stage;
- and
- in each stage, except for the highest-voltage-stage, the electronic components are directly soldered to a bottom-side of the circuit board of the higher voltage stage, the bottom-side of each circuit board being opposite of the top-side.
