Abstract

The Center for Artificial Muscle (CAM) is in the process of designing a new type of Vascular Assist Device (VAD) that uses the mechanical and electrical properties of Dielectric Elastomer Actuators (DEAs). The main challenges with these actuators are that they require very high voltages to operate (in the order of the kV) and that they will be implemented inside the body. A solution amongst various possibilities to power them is to transfer energy by induction through the skin and to generate the high voltage directly on the secondary coil (inside the body). However, power and data also need to be sent to a microcontroller inside which works at a significantly lower voltage (in the order of the V).

Voltage regulator

A voltage regulator is a system designed to automatically maintain a constant voltage. A voltage regulator may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC voltages. Electronic voltage regulators are found in devices such as computer power supplies where they stabilize the DC voltages used by the processor and other elements.

High-voltage direct current

A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems. Most HVDC links use voltages between 100 kV and 800 kV. However, a 1,100 kV link in China was completed in 2019 over a distance of with a power capacity of 12 GW. With this dimension, intercontinental connections become possible which could help to deal with the fluctuations of wind power and photovoltaics.

High voltage

High voltage electricity refers to electrical potential large enough to cause injury or damage. In certain industries, high voltage refers to voltage above a certain threshold. Equipment and conductors that carry high voltage warrant special safety requirements and procedures. High voltage is used in electrical power distribution, in cathode ray tubes, to generate X-rays and particle beams, to produce electrical arcs, for ignition, in photomultiplier tubes, and in high-power amplifier vacuum tubes, as well as other industrial, military and scientific applications.
