FIELD: electricity.
SUBSTANCE: proposed excitation and control device supplies the required switched current to load containing circuit of one or more electronic devices. Voltage conversion device on the basis of input control signal converts value of voltage obtained from voltage source to the other value required on the side of high voltage of load. Control device of change of light intensity provides control of activation and deactivation of load and can also provide current limiting means. Feedback means are connected to voltage conversion means and to current read-out device and supplies control signal to voltage conversion means, which indicates voltage drop in current read-out means which represent the current passing through load. Based on the received control signal, voltage conversion means can regulate its output voltage so that direct switched current can be supplied to load.
EFFECT: higher operating efficiency.
