In case you had either a butterfly capacitor or an air capacitor, you can''t drive ir directly. This is because you''d only have 100 steps to tune your antenna. My advice is using a modified 12v 28BYJ step motor. This motor is the cheapest on the market . It has a gear box 2000 step per revolution. It is enough to tune your capacitor precisely.
The soft starter based on the magnetic control reactor (MCR) has many advantages, including high reliability, flexible control, and so on. However, during the starting process, the motor side current is the same as the system side current, so when the super-large-capacity high-voltage motor is started, the system short-circuit current must be ...

This article presents a novel flux-cancellation-based modular multilevel converter (MMC) with power decoupling capability. Conventional MMC suffers from low-frequency (fundamental and second-order) ripple power in the submodule (SM) capacitors. The low-frequency ripple power makes the SM capacitors bulky, responsible for a significant portion of the volume and weight …

When single-loop inverter-side current control is used in the LCL-type inverters, there may be more than one stable region with regard to computation delay in control path. The system is stable if computation delay is small enough, but it, named as the first stable region, may be too narrow to finish the control codes in high-frequency system. On the other …

This magnetic control of the PSR and NERH is observed experimentally and in the model (see figure 4(b)–(e), (g)). The model clearly shows that the physical origin of this magnetic control of the PSR and NERH is the local enhancement of the plasma density at the powered electrode induced by increasing the local magnetic field, i.e. the MAE.
