摘要： A lamp ballast is provided requiring less size and cost for powering a discharge lamp. An inverter circuit converts a DC voltage from a DC power source into a voltage having a determined frequency, and supplies the converted voltage to the discharge lamp inserted between a pair of output ends of the inverter. A resonant circuit includes an auto-transformer and a resonant capacitor, and supplies an output voltage corresponding to a frequency of the rectangular wave voltage of the power supply circuit to the discharge lamp. A voltage detection circuit detects an output voltage of the resonant circuit based on a potential of the resonant capacitor. A control circuit has a startup control mode to set the frequency of the rectangular wave voltage based on the detected voltage from the voltage detection circuit, wherein the output voltage of the resonant circuit exceeds a starting voltage of the discharge lamp.

摘要： A transformer has a bar-shaped ferrite core, an inner winding wound directly around the ferrite core, an outer winding wound over the inner winding, and a dielectric shield surrounding the outer winding. The outer winding has its circumference covered by a dielectric sheath, and has an intermediate winding portion between its winding start end and its winding stop end. The dielectric sheath in the intermediate winding portion is spaced from each other along the axis of the ferrite core to leave thereat a gap which is filled with a molding material. By provision of the gap between the dielectric sheath of the outer winding, the molding material forming the dielectric shield can be easy to flow in between the dielectric sheath of the outer winding and the inner winding, avoiding the void from appearing between the inner and outer windings for attaining stable electrical characteristic.
