Elevated Frequency

The article presents information about the composition of the equipment of resonant power transmission systems. The resonant systems of electrical energy transmission by single-wire cable or overhead lines at elevated frequency include frequency conversion devices, power transmission lines, and devices for the reverse transformation of electrical energy to the voltage required by the consumer. In contrast to traditional systems of electrical power transmission, resonant systems are being operated on an elevated frequency of 5-15 kHz, a power transmission line voltage is 1-10 kV. In this case resonant transformers are used. The frequency of the power transmission system is set by the resonant transmitting transformer; the receiving transformer is a wideband step-down one.The main components of the resonant transmitting transformer are a power resonant circuit and a step-up/step-down winding. The maximum output power of the converter depends on the voltage supplied to the circuit, circuit voltage, circuit capacitance, frequency, and other parameters. One can change the transmitted power by changing the transmission frequency, for example, for lighting systems.Due to the fact that resonant power transmission systems operating at elevated frequency are less demanding on the grounding quality, they are more efficient compared to single wire ground return line operating at a constant current and an alternating current of commercial frequency

Transcutaneous Energy Transmission

Transcutaneous energy transmission systems (TETS) wirelessly transmit power through the skin. TETS is particularly desirable for ventricular assist devices (VAD), which currently require cables through the skin to power the implanted pump. Current implantable TETS systems are not optimized for high power VAD applications. Optimizing the inductive link of the TET system is a multi-parameter problem. Most current techniques to optimize the design simplify the problem by combining parameters leading to sub-optimal solutions. In this paper we present an optimization method using a genetic algorithm to handle a larger set of parameters, which leads to a more optimal design.
