A neon sign transformer for operating a neon tube from a mains frequency alternating current comprising: a filter for filtering electro-magnetic interference from said alternating current; a first rectifier for rectifying said filtered alternating current so as to produce a low level alternating current: electrical circuit driver for generating a high frequency low level alternating current; an electrical power circuitry for generating a high frequency high level alternating current then rectified to provide said high level direct current for energizing said neon tubes. |
