Reduced component drive circuit

A drive circuit rectifying DC and AC signals to drive an electrical load comprising:

• (a) a first bidirectional switch electrically connected at an input side to a piezoelectric transformer and at an output side to an electrical load;
• (b) a comparator circuit electrically connected about said first bidirectional switch, said comparator circuit comparing a present voltage value at said electrical load and a desired voltage value at said output side, said comparator circuit closing said first bidirectional switch thereby directing a high-frequency signal from said piezoelectric transformer into said electrical load when said high-frequency signal crosses said present voltage value, said comparator circuit opening said first bidirectional switch when said high-frequency signal reaches said desired voltage value;
• and
• (c) a second bidirectional switch electrically connected at a first end between said piezoelectric transformer and said comparator circuit and terminated at a second end, said first bidirectional switch and said second bidirectional switch driven in opposite phase and charge direction relative to said electrical load.

A power distribution system rectifying DC and AC signals to drive a plurality of electrical loads comprising:

• (a) a power supply;
• (b) a bulk converter converting a power from said power supply to a level DC power;
• (c) a power storage element storing said level DC power;
• and
• (d) a plurality of drive elements each electrically connected at a first end to said power storage element and at a second end to an electrical load, each said drive element comprised of an AC generator electrically coupled to a piezotransformer electrically coupled to a drive circuit, said drive circuit comprised of a bidirectional switch electrically connected at an input side to said piezoelectric transformer and at an output side to said electrical load and a comparator circuit electrically connected about said bidirectional switch, said comparator circuit comparing a present voltage value at said electrical load and a desired voltage value at said output side, said comparator circuit closing said bidirectional switch thereby directing a high-frequency signal from said piezoelectric transformer into said electrical load when said high-frequency signal crosses said present voltage value, said comparator circuit opening said bidirectional switch when said high-frequency signal reaches said desired voltage value.
