ABSTRACT:
A voltage converter transforms a high voltage alternating current (ac) input source into a lower voltage direct current (dc) output voltage. The line frequency of the ac current switches an electronic switch to alternately reconfigure a combination of capacitors and diodes to perform energy storage and effect voltage division. The dc output voltage is approximately one half of the peak ac input voltage at no load.
