DC to DC ConverterThe circuit below is a DC to DC converter using a standard 12 VAC center
tapped power transformer wired as a blocking oscillator. The circuit is not very
efficient but will produce a high voltage usable for low power applications. The
input battery voltage is raised by a factor of 10 across the transformer and
further raised by a voltage tripler consisting of three capacitors and diodes
connected to the high voltage side of the transformer. The circuit draws about
40 milliamps and should operate for about 200 hours on a couple of 'D' alkaline
batteries. Higher voltages can be obtained by reducing the 4.7K bias resistor.
