An electrical power supply system for an electric transport refrigeration unit. The electrical power supply system is for providing AC power to a refrigeration system and includes: a DC power source for providing a DC voltage via a low voltage line and a high voltage line; an inverter for receiving the DC voltage and converting it to a three phase AC voltage for powering the refrigeration system; and an electromagnetic compatibility, EMC, filter between the inverter and the refrigeration system. The EMC filter uses a common mode current path that connects to a DC link, where the DC link is provided between the high voltage line and the low voltage line of the DC power source. The common mode current path is hence coupled to the DC link in order to provide a floating current connection for common mode current from the EMC filter.
