Abstract
A voltage and frequency converter device for converting a primary voltage and frequency from an electrical supply to a secondary voltage and frequency particularly useful in powering the timing mechanisms in appliances made to operate at the secondary voltage and frequency, includes a rectifier circuit for converting the alternating current oscillating at the primary frequency to direct current, circuitry for causing the current to oscillate at the second frequency and for converting the primary voltage to the secondary voltage. The output of the converter is preferably coupled only between the power source and the timing circuitry of the appliance but may also be coupled to the power circuitry for motors and the like provided the converter is further configured to generate a true sine wave output. The invention further includes a wiring configuration for a dwelling whereby the voltage and frequency converter is interconnected between the power source and the electrical wiring of the dwelling to provide the secondary voltage and frequency to at least one secondary outlet and the primary voltage and frequency to at least one primary outlet in the dwelling whereby electrical applianc…
