Abstract

The invention provides a nickel-cadmiun storage battery charging adjuster employing a satellite power supply, relates to the field of charging a storage battery pack employing the satellite power supply, and aims at solving the problem of shortage of an adjusting device for ensuring stable charging and stable charging terminating for the storage battery pack through the satellite power supply at present. A boost topological structure circuit carries out boost conversion on input bus voltage; a current and voltage sampling feedback control unit samples charging output current and voltage and synthesizes the current, the voltage and a signal to finish obtaining and outputting of a feedback signal; a PWM control unit outputs a corresponding pulse width signal through the feedback signal to drive an NMOS tube of the boost circuit; and the control unit receives a charging enable signal obtained by amplifying an error of the bus voltage of the satellite power supply, controls an overall charging circuit to be connected when the signal is effective, obtains operating temperature and voltage of the storage battery pack and stops charging when the voltage of the storage battery pack reaches charging terminating voltage corresponding to a temperature monitoring signal, so that the charging process is completed. The nickel-cadmiun storage battery charging adjuster is applied to a bus for charging the storage battery pack.
