Abstract

Uma unidade de fonte de alimentação para uma fonte de radiação de raios X (10) compreendendo um gerador de alta tensão (4) para prover uma corrente básica para a operação de um tubo de raios X (10), um gerador de forma de onda (6) e um transformador de pulso (2) para prover picos de tensão sobreposicionáveis e uma unidade de controle (8) para gerar um contrapeso em uma entrada (12) do transformador de pulso (2) para evitar efeitos de saturação. A provisão de diferentes padrões de forma de onda de referência leva à prevenção de sobressinal e oscilações.
