A method of voltage regulation of an electrical power sub-system (referred to as an electric circuit) of a motor vehicle, in which the electric circuit comprises a generator 12 providing an output voltage, a primary load 13 switchable between an on-state and an off-state and a ballast load 21 which is also switchable between an on-state and an off-state. The method comprises identifying that the primary load is required to be either switched to the off-state or to the on-state and, in response, co-ordinating switching the ballast load between the off-state and the on-state with switching said primary load to its off-state; or co-ordinating switching the ballast load between the on-state and the off-state with switching said primary load to its on-state, such that the voltage of the electric circuit is regulated. Synchronising switching of the loads in this way balances the load on the electrical circuit such that voltage spikes and voltage dips may be minimised or eradicated. |
