FIELD: electricity.
SUBSTANCE: diagram of a flyback quick start driver includes a voltage input device, a transformer comprising a primary winding, a secondary winding, and an auxiliary winding, an excitation control device for the primary winding of the transformer, a load device, and a control device with feedback. The load device performs the charging process based on the DC current from the voltage input device to allow the output voltage to be brought to the starting value that is applied to the excitation device. The excitation device outputs a control signal for excitating the primary winding. Thus, voltage is generated on the auxiliary winding. The control device with feedback receives voltage of the auxiliary winding and determines, whether to stop charging the load device or not based on voltage of the auxiliary winding.
EFFECT: acceleration of excitation and reduction of energy consumption.
