variable capacitor
Variable capacitor is gradually unable to meet the requirements due to its insufficiencies such as more conversion stages, low efficiency, and poor transient response. High-frequency ac power distribution system (HFAC PDS) proposed has become an alternative because of its merits such as fewer conversion stages, higher efficiency, faster response, high power density, distributed heat profile, and potential For connector-less power transfer.

Static var compensator is one of the valuable applications for power electronics technology. For ac power transmission and distribution system, various types of static reactive power compensator have been proposed. Shunt compensation is widely used to improve power factor and voltage stability. A static synchronous compensator (STATCOM) based on voltage source converter (VSC) can be said to be the most advanced shunt-type reactive power compensator. In contrast with thyristor-based reactive power compensators,

...moremagnetic coupling
Magnetic coupling are often used in PLL (phase locked loop) circuits for dynamic frequency control. However, the voltage and current ratings of varactors are too low to be used in most power electronic circuits. This paper proposes a transistor controlled variable capacitor (TCVC), which functions similar to varactors in that its equivalent capacitance can be controlled by a DC voltage. However, the TCVCcan handle high voltages and currents so that it can be used in DC-AC power converters of Wireless Power Transfer (WPT) systems such as an autonomous push pull resonant converter to adjust its ZVS (zero voltage switching) frequency so that the operating frequency of the system can be stabilized to simplify the circuit and EMI filter design particularly for WPT systems with multiple power pickups, while maintaining soft-switching operation of the converter against magnetic coupling and load variations. The relationship between the equivalent capacitance of the TCVCand the DC control voltage is developed by theoretical analysis and verified by experimental results.
...moreMagnetic Clutch
Magnetic clutch are widely used in the industry to convert dc voltage to ac Voltage. The VSIs have some major problems such as inability to increase the voltage and causing damage to the converters when the switches of a leg are turned ON at the same time. In order to solve these problems, inverters with impedance network can be used. The conventional Z-source inverter (ZSI) increases the level of output voltage and can also withstand short-circuit condition in the legs of inverter that is called shoot through (ST).
