Abstract:
In a system including a power supply, such as a rectifier, which supplies power to a load and in which a back-up battery is arranged between the power supply and load, a current controller is configured to control the recharging current supplied to the back-up battery. The current controller includes a variable resistance which is altered dependent upon whether more or less current is to be used for recharging of the back-up battery. The use of the current controller ensures that sufficient current is available for the load during the recharging process, even in a situation where the back-up battery requires a high level of recharging.
