A capacitive wireless power transfer (C-WPT) system uses an electric field to transmit power through a physical isolation barrier which forms a pair of ac link capacitors between the metal plates. However, the physical dimension and low dielectric constant of the interface medium severely limit the effective link capacitance to a level comparable to the main switch output capacitance of the tra...
This paper presents a step up DC-to-DC converter with hybrid switch capacitor technique having high voltage conversion ratio with small switch voltage stress . The converter is suitable for the applications where high voltage conversion is required.

This paper presents an implementation of open loop and closed loop control of Quadratic boost converter using PID controller. Quadratic boost converter consists of boost converter and fly back converter driven by a single switch. Quadratic boost converter QBC is designed especially for regulating the DC interface between various micro sources and dc-ac inverter to electricity grid. Quadratic b...
One of the most important control methods in induction motor is direct vector control. This method is based on rotor flux estimation using stator voltage. The machine voltage is low in The voltage model for low speed and voltage drop over the stator resistance is not negligible in front of stator voltage. Thus the stator flux estimation using voltage method is not precise. Some methods are base...
A novel approach is proposed for a high step-up and high efficiency converters with a low switch stress. The integrated boost-flyback converter uses coupled-inductor techniques to achieve high step-up voltage with low duty ratio, and thus the slope compensation circuit is disregarded. The proposed circuit topology improving highgain ratio, increasing efficiency, reducing the secondary side of c...
