The power supply arrangement receives an input voltage and includes: voltage boost means (24,24) for increasing the input voltage to a power supply output voltage (Vsupply), the voltage boost means including a three-phase boost system (124) including first, second and third inductors (74a,74b,74c); switch means (28; 28a,28b,28c) operable between open and closed states to control current flow through said voltage boost means (24,124), and a controller (14) for generating at least one control signal (130; 230,64,130A,130B,130C) for the switch means to control switch status based on an injection running condition, thereby to regulate the power supply output voltage (Vsupply).",
