Variable power inverter
Inverters are components used to control speed or torquecontrol for an electric motor. Inverters take AC mains and rectify it into DC. They are components that also can turn DC current into AC current. They are known by a number of different names but the correct term is actually. Variable frequency drives are found in a number of different applications. You will find them in lifts and elevators to control the speed of the hoist. You may experience this when. The purpose of an inverter drive is to convert AC mains (single-phase or three-phase) into a smoothed DC (direct current) supply to operate a motor. Inverters also introduce the ability to control speeds, acceleration and deacceleration time, braking methods,. You can set the frequency of an inverter by a number of different methods. It depends on what brand you use and also the number of available commands and inputs/outputs the inverter has. You should always look at the inverter's manual to see what parameters can.

Variable capacitor antenna
Capacitors are incredibly simple. a pair of conductive bits, separated by some dielectric media, and you just charge up that field between them until it eventually arcs if the voltage is too high. I started looking more into what material options for dielectric exist, and how changes in dielectric strength and constant. Unfortunately while reading about capacitor dielectrics I came across a comment saying that even a small air gap between two dielectric. The calculation that killed this path of DIY capacitors for magloops was that of power dissipation inside the dielectric material. I had seen tables of “tangent loss coefficient”, but thought that *those numbers seem small. With dielectric losses understood, my choices returned to an air variable capacitor, or a vacuum variable cap. Seeing that most any size. A variable capacitor is a whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or as a variable, e.g. for in.
