Abstract (en)
[origin: GB2487763A] A voltage regulator 11, arranged to supply an output voltage to a load at more than one voltage level, has a means to adjust an output voltage in response to a control signal, and an energy measurement means 8 to measure the power at each voltage level. The voltage regulator outputs a number of voltages e.g. the mains supply voltage and a lower optimum voltage that reduces power consumption of a load. The regulator is switched periodically between voltage levels and the energy measurement means is used to measure energy consumption at each level to determine e.g. the reduction in energy usage at the optimum voltage. The energy measurement means may be associated with a controller 7 that switches the regulator to the voltage with the lowest power consumption. The voltage regulator may be a transformer 3 with multiple taps providing the different voltage levels via switches 4 - 6.
