Abstract
A DC high voltage generator includes an AC power supply, an AC-DC rectifier and means to stabilize the DC high voltage generator against load variations. The stabilizer means uses at least two electro-magnetically coupled resonant circuits, which compensate the load variations at an operating frequency in such a way that the output voltage is essentially constant.
Claims25
A DC high voltage generator comprising:
- an AC power supply;
- an AC-DC rectifier;
- and
- means for stabilizing said DC high voltage generator against load variations,
- wherein said stabilizing means stabilize said DC high voltage generator by using pulse width modulation at a constant operating frequency with at least two electro-magnetically coupled resonant circuits compensating each others load variation dependency at an operating frequency in such a way that the output voltage is essentially constant.
A method for stabilizing a DC high voltage generator, which has an AC power supply and an AC-DC rectifier, against load variations comprising the step of:
- coupling two or more resonant circuits to compensate for a load variation of one of the resonant circuits such that the output voltage is substantially constant.
The method of claim 36 further comprising forming an interface between the AC power supply and the AC-DC rectifier using at least one of the resonant circuits.
