  • Power supply system
    Patent number: 10638579
    Abstract: The invention relates to power supply systems. There is provided an apparatus and a method for supplying electric power to an electric device. In the method an indication of a desired power level to be supplied to the electric device is obtained. Electric power is received as DC power by a constant current regulator unit, which inverts the DC power to AC power and supplies the AC power to a reactance (T1) to be transformed to an output power. The output power is supplied from the reactance (T1) to the electric device. The method further comprises adjusting the AC power supplied to the reactance (T1) by using at least two of the following: voltage level of the AC power; the frequency of the AC power; a waveform of the AC power.
