Abstract
The invention discloses a power pack starting circuit of an internal-combustion motor train unit, which is composed of a charger, a storage battery, a supercapacitor, a current limiting resistor and a starting motor, wherein the storage battery and supercapacitor are connected in parallel; and the supercapacitor is directly connected with the starting motor as a main starting power source. In order to lower the capacity, weight and procurement cost of the storage battery, the current limiting resistor is connected between the storage battery and supercapacitor in series, so that the storage battery only supplies a small part of current when the power pack starts. The low-capacity medium/low-factor storage battery and supercapacitor have the advantages of light weight and small size, and are convenient for mounting and use. Finally, the storage battery and supercapacitor are connected with the charger in parallel, and therefore, the charger charges the supercapacitor in the storage battery feeding or failure process. When the charger fails, the storage battery charges the supercapacitor, thereby providing stability and reliability for the circuit.
