A control arrangement for use in controlling the electrical supply from a power supply unit including an internal capacitance to an output is described, the control arrangement comprising an inductor, a switch arranged in parallel with internal capacitance, and a controller operable to control the operation of the switch such that closing of the switch results in the formation of an LCR circuit, the internal capacitance forming the capacitance of the LCR circuit. An associated control method is also described. |
