Abstract (en)
[origin: EP0681415A1] The circuit for supplying power to an electrical discharge lamp includes an oscillator providing a sinusoidal signal (Vcom) with few significant harmonics. The signal offers few significant harmonics and has no steep fronts. This signal is applied to an amplifier (4) which in turn provides an output signal for application to the discharge lamp (2). The operation of the amplifier is linear when the lamp is illuminated. The amplifier does have a transitory nonlinear regime when it generates firing pulses to start up the discharge lamp (2). <IMAGE>
