Abstract: A miniaturized VHV transformer/rectifier for surface mounting on a screen-printed ceramic substrate. The primary winding and secondary windings are wound on separate limbs of the magnetic circuit which are sufficiently far apart to obtain a considerable leakage self-inductance. The secondary winding is formed by a stack of pancake coils each including a respective winding and the associated diode bridge along with their respective connections. The primary is cemented to a ceramic interface plate which is metallized on its rim to make a transfer plate coinciding with the surface of the receiving substrate.

Abstract: The mean value of a continuous function controlled by a constant-period all-or-none signal is regulated and stabilized by controlling the maximum value of the continuous function in dependence on a sawtooth signal having a variable period, each leading edge of the sawtooth signal being in synchronism with the peaks of the regulated signal.
