摘要: An electronic ballast for supplying a lamp comprises a control loop for controlling the rms value of an operational parameter so as to be constant. In the control loop, the actual rms value of the parameter is generated as a linear combination of its average value and its peak value.

摘要: A lamp is operated using a DC-AC converter provided with switches and a control circuit for controlling the switches and generating a high-frequency AC lamp current. In each half period of the control signal generated by the control circuit, each of the switching elements is rendered conductive during successive time intervals. The lamp can be dimmed without instabilities by adjusting the second time interval in each half period of the control signal.
