Abstract:
A voltage converter circuit comprising:a resonant sub-circuit;said resonant sub-circuit comprising a transformer device;said transformer device having an input portion and output portion,said input portion comprising an electroactive layer disposed between a first electrode layer and a second electrode layer; andsaid output portion comprising a third electrode layer adjacent an electroactive layer;said resonant sub-circuit further comprising an inductor (L1) electrically connected in parallel with said input portion (1A) of said transformer device between said first electrode layer (4) and said second electrode layer (6);a first conductor adapted to be connected to a DC first voltage;a second conductor adapted to be connected to a DC second voltage, said DC first voltage being greater than said DC second voltage;said first conductor being electrically connected to said first electrode (4) and to a first end of said inductor (L1);a switching device (Q1),said switching device having a control input conductor (G), a first switch terminal (D) and a second switch terminal (S);said first switch terminal (D) being electrically connected to said second electrode layer;said second switch terminal (S) being electrically connected to said second conductor;a first resistor (R1) in parallel with said inductor (L1), said first resistor being electrically connected at a first end to said inductor (L1) and said first conductor and said first electrode, and said first resistor being electrically connected at a second end to said control input conductor (G) of said switching device (Q1);a second resistor (R2) in parallel with said switching device (Q1), said second resistor being electrically connected at a first end to said control input conductor (G) of said switching device (Q1), and said second resistor being electrically connected at a second end to said second terminal (S) of said switching device (Q1);and a first output conductor connected to said third electrode;whereby a DC voltage potential applied between said first conductor and said second conductor may be converted to an AC voltage potential between said first output conductor and second switch terminal (S).
