FIELD: instrument making.
SUBSTANCE: half-bridge converter is controlled with variable frequency generator and relative pulse duration, which in its turn is controlled as per relative pulse duration with low pass filter signal, and as per frequency - with current sensor of the lamp. Priority signal supplied from rectifier connected to the lamp is supplied to control input as per generator frequency. Outputs of current sensor of the lamp and voltage rectifier of the lamp are connected to power control device. Power control device has logic unit analysing operating modes of the lamp and ballast as a whole and generating control and correction signals. Outputs of power control device are connected to the lamp lighting device and to generator. In addition, to electronic ballast there built in is bidirectional modem of data transmission via network wires, dedicated line or radio channel which is connected to power control device.
EFFECT: enlarging functional capabilities.
