CONTROL DEVICE FOR POWER SUPPLY CONTROL SYSTEM

摘要

A control device for a power supply control system comprises a main power supply for storing power from a power generator and supplying power to a load and an electrical double layer capacitor for storing power from the power generator and the main power supply. The electrical double layer capacitor has at least a first charging state region and a second charging state region that is higher than the first charging state region. During driving of the power generator, a control means operates a DC/DC converter in a charging mode. During the normal time of the main power supply, the control means controls the power supply control system so that power is supplied from the main power supply according to a load, and operates the DC/DC converter in a discharging mode and uses the second charging state region to perform control so that an auxiliary power supply assists in supplying the power. During the failure time of the main power supply, the control means operates the DC/DC converter in the discharging mode and uses the first and second charging state regions to perform control so that the auxiliary power supply assists in supplying the power.
