The system includes a supporting device having a first portion fixedly mounted to a main frame and a second portion attached to a door. The second portion being movable about a hinge axis portion that connects the first portion to the second portion. An energy transmitting source is connected to a power frequency generator. The power frequency generator is connected to a power source and configured to couple an oscillating signal to the energy transmitting source. The energy transmitting source is mounted on the hinge axis portion of the supporting device. An energy receiving device is magnetically coupled to the energy transmitting source to receive a power signal from the energy transmitting source. The energy receiving device is mounted on the second portion of the supporting device at a fixed distance from the energy transmitting source. The energy receiving device receives the power signal from the energy transmitting source to deliver the power signal to powered components associated with the door. The power delivery is uninterrupted during opening and closing of the door.
