Quick-start high-voltage boost

Abstract

In one implementation, a voltage boost assembly including a boost converter having a capacitive element arranged at an output, and an inductive element connectable to an electrical supply. The voltage boost assembly also includes a sensor assembly provided to generate a quick-start enable signal in response to detecting that an electrical condition relative to an electrical output of the boost converter has breached a first threshold. The voltage boost assembly further includes a quick-start module responsive to the quick-start enable signal, and configured to drive the boost converter at a relatively high duty-cycle and so that the boost converter delivers an output current that satisfies a second threshold in order to charge the capacitive element arranged at the output.

What is claimed is: 
     
         1 . A method of ramping up the output of a boost converter, the method comprising:
 sensing that an electrical condition relative to an electrical output of the boost converter has satisfied a first threshold;   generating an enable signal;   driving a boost converter to deliver an output current that satisfies a second threshold in order to charge a capacitive element arranged at the output of the boost converter.
