FIELD: electricity.
SUBSTANCE: device includes flyback power supply, separating capacitor, thyristor and thyristor control unit which is made on the basis of three transistors of various kinds of conductivity and connected to each other. At that, control unit includes stabilitron and current control on the fourth transistor.
EFFECT: simple and reliable scheme of starting-and-regulating device (SRD) for feeding the gas-discharge lamp without using ballast capacitor or throttle, reducing power consumption at increased light efficiency of gas-discharge lamps, brightness control of gas-discharge lamp within wide limits (50-100%), use of burnt out gas-discharge lamps which do not operate with the majority of existing SRD; device is not sensitive to current overloads and short circuits, is switched off automatically up to elimination of short circuit at the output.
