Abstract:
An electronic ballast circuit having at least two distinct switching cycles also includes an anti-striation feature. More particularly the electronic ballast includes an input section configured to receive an input from a power source. A resonant section receives the signals from the input section in order to generate a resonant signal. An anti-striation component is connected within the electronic ballast circuit to affect operation of the resonant section, which results in an affected resonant signal. A switching arrangement is configured to receive the affected resonant signal from the resonant section and anti-striation component, and is further configured to generate an asymmetric output signal due to the affects of the anti-resonant component, wherein the anti-striation component causes parameters of the resonant section of the electronic ballast circuit to be different for different switching cycles of the electronic ballast circuit. An output section is provided to output the asymmetric output signal to a lamp system.
