· Among different kinds of TENGs the rotary freestanding TENG (RF-TENG) has many advantages to be a promising power supply with high voltage. It has extraordinary output performance and capacity to reach an open-circuit (OC) voltage much higher than 10 000 V with relatively high frequency. Moreover as the electrodes are independent from the moving parts the RF-TENG could be easily driven by rotating motor at different speeds and serve as a stably high

· High Power Density Cost-Effective MV DC Aircraft Cable- 1 171 829. To make the power density of electric aircraft closer to conventional aircraft an electric power system (EPS) with high power delivery and low system mass is necessary. As an essential component of aircraft EPS cables are necessary to transmit power from one node to another.
· For the majority of high power applications the power electronic control circuitry is contained on a separate board (typically PCB) from the high power switching devices (MOSFETs or IGBTs) often time with a third stage containing the power magnetics and filters .Through this separation the problems are isolated the electronics engineer focuses upon the topology of the converter design
Dowty Seals are also known as Bonded Seals or Dowty Bonded Washers. They are high pressure seals used in the Mechanical Hydraulic and Pneumatic sectors. Dowty Seals have generally replaced copper washers in high pressure applications. A trapezoidal shaped rubber sealing element is bonded to the inner of a metal washer to produce the finished part.
