Abstract
A circuit for use in providing high voltage power to a neon bulb positioned on the vehicle utilizing the vehicle DC battery as the power source. The circuit includes an invertor, a transformer, and a rectifier. The invertor receives low voltage DC from the vehicle battery, converts the low voltage DC to a low voltage AC drive voltage, and delivers the AC drive voltage to the transformer primary for conversion to a high voltage AC at the transformer secondary. The rectifier receives the high voltage AC from the transformer secondary, converts the high voltage AC to high voltage DC, and delivers the high voltage DC to the neon bulb. Since the power delivered to the neon tube is DC there is less need to shield the tube with respect to electro magnetic emissions and parasitic losses in the wire runs between the battery and the neon tube are significantly reduced.
