Abstract
A power supply including a piezoelectric transformer mounted and electrically connected to a defined board region of a printed circuit board having circuit components for forming the power supply together with the piezoelectric transformer. The transformer has FPC for connecting the transformer and the printed circuit board and is bound together with the board region by a wrapping sheet. In an embodiment, the board region is defined by a slit through which the wrapping sheet is wrapped. In another embodiment, the FPC has lugs standing up thereon to connect with the electrodes of the transformer. In another embodiment, a hard plate supports and covers the FPC and the transformer on the printed circuit board. In the other embodiment, the FPC is formed into a cover case and covers and holds the transformer element when is fixed to the printed circuit board.
