Cell relay is an implementation of fast packet-switching technology that is used in connection-oriented broadband integrated services digital networks (B-ISDN, and its better-known supporting technology ATM) and connectionless IEEE 802.6 switched multi-megabit data service .
Adaptive voltage scaling is used to address the energy-saving requirements of application-specific integrated circuits, microprocessors and system on a chip circuits. It is also well-suited for high-volume systems such as data centers and wireless base stations, as well as power-constrained applications such as portable devices, USB peripherals ...
There is the alternative option of indirect energy conversion by employing the Indirect Matrix Converter (Fig. 5) or the Sparse matrix converter which was invented by Prof. Johann W. Kolar from the ETH Zurich. As with the DC-link based VSI and CSI controllers (Fig. 2 and Fig. 3), separate stages are provided for voltage and current conversion ...
Power-system automation is the act of automatically controlling the power system via instrumentation and control devices.Substation automation refers to using data from Intelligent electronic devices (IED), control and automation capabilities within the substation, and control commands from remote users to control power-system devices.
The most widely used electronic switch in digital circuits is the metal–oxide–semiconductor field-effect transistor (MOSFET). [2] The analogue switch uses two MOSFET transistors in a transmission gate arrangement as a switch that works much like a relay, with some advantages and several limitations compared to an electromechanical relay.
Thus, the high efficiency reached by the switching power converters is related to the use of switching devices, energy storage elements and transformers, through proper modulation activity of the switches to convert the available DC or AC and voltage or current signal waveforms of the power source into the AC or DC waveforms needed by the load.

Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
