This paper proposes a new control method of a direct ac-to-ac converter consisting of two half-bridge converters and a series-resonant circuit. This circuit converts the ac input power from the utility grid to a high-frequency ac output without any dc stage.

This paper presents a new interleaved active clamp forward converter for low and wide input, and high current output applications. In the proposed converter, the operating duty ratio can be extended over 0.5 due to the additional powering path resulting from additional series-connected secondary windings from each transformer.

In this study, a closed loop feed-forward direct current (DC)–DC converter has been designed which operates solely on two supercapacitor modules. This is an innovative new design where the challenge was to maintain the constant output voltage when the input voltage of the converter is decaying continuously as a function of time as long as the output load draws current.

This paper presents an area- and power-efficient application-specified integrated circuit (ASIC) for 3-D forwardlooking intravascular ultrasound imaging. The ASIC is intended to be mounted at the tip of a catheter, and has a circular active area with a diameter of 1.5 mm on the top of which a 2-D array of piezoelectric transducer elements is integrated.
