Claims
- 1. A DC high voltage generation system for medical equipment comprising:
- a variable magnetic leakage transformer including primary, secondary and control windings;
- a capacitor type multiple boosting circuit comprising a plurality of capacitors cascaded through diodes to each other, said capacitor type multiple boosting circuit being coupled to said secondary of said variable magnetic leakage transformer and forming a resonant circuit with said variable magnetic leakage transformer;
- a driving circuit coupled to said primary winding of said variable magnetic leakage transformer for driving said system at a resonant frequency of the resonant circuit formed by said capacitor type multiple boosting circuit and said variable magnetic leakage transformer; and
- a pulse-amplitude feedback control circuit coupled to said control winding and a load of said DC high voltage generation system for pulse-amplitude controlling an output voltage of said DC high voltage generation system, said pulse-amplitude feedback control circuit comprising:
- a means for detecting a magnitude of said output voltage to said load;
- a means for presetting a reference voltage;
- a means for comparing said detected voltage with said reference voltage to produce a deviation voltage; and
- control transistors coupled to said control winding to act as a constant current source which in response to said deviation voltage pulse-amplitude control said output voltage.
