A connection apparatus for controlling the supply of electrical power to a load, the connection apparatus comprising first and second electrically controllable devices connected in parallel to each other and in series with the load; wherein the first and second electrically controllable devices are dissimilar, and where a safe operating area product of voltage, current and safe operating area time for the first device is greater than the product of voltage, current and the same safe operating area time for the second device, and an on state resistance for the second device is less than an on state resistance for the first device, and where a controller is provided to use the first device for a first period of time to power up the load, and thereafter the second device is used to maintain power to the load.

Connection apparatus

A connection device for connecting a load to a power supply, comprising at least first and second current control devices arranged in parallel between the power supply and the load, and a controller arranged to switch the current control devices on in sequence for temporally overlapping on periods.
