Abstract:
1. A connection apparatus for applying an established 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, wherein the first electronically controllable device has a greater operating characteristic rating, defined by a product of drain source voltage and drain current for a specified on state operating time, than an operating characteristic rating of the second electronically controllable device, and an on state resistance for the second electronically controllable device is less than an on state resistance for the first electronically controllable device, and wherein a controller is provided to use the first electronically controllable device for a first period of time that the established supply of power is applied to the load, and thereafter the second electronically controllable device is used to maintain power to the load.
