Three phase voltage tripler

A method, comprising:

• arranging first, second, and third capacitive elements;
• selectively switching connections among said capacitive elements and between said capacitive elements and a reference voltage during first, second, and third periods;
• and
• charging said first capacitive element to a first voltage level during said first period, said second capacitive element to a second voltage level during said second period, and said third capacitive element to a third voltage level during said third period, wherein said third voltage level is greater than said second voltage level and said second voltage level is greater than said first voltage level.

A three-phase voltage tripler, comprising:

• first, second, and third capacitive means for providing capacitance;
• and
• switching means for selectively switching connections among said capacitive means and between said capacitive means and a reference voltage during first, second, and third periods,
• wherein said switching means charges said first capacitive means to a first voltage level during said first period, said second capacitive means to a second voltage level during said second period, and said third capacitive means to a third voltage level during said third period, and wherein said third voltage level is greater than said second voltage level and said second voltage level is greater than said first voltage level.
