- on Power Supplies

Electric motors used in robot applications often make sudden and heavy demands on their power supply. Although the batteries normally used have a low internal resistance, they nevertheless sometimes have difficulty maintaining their output under load and can be damaged by current spikes. Not all the electronics in the robot can cope with these effects, the voltage regulation provided by ordinary three-terminal devices not always being up to the job. This electronic voltage stabiliser is a solution to that problem.
