Main task of power semiconductor converter is transfer of electrical energy from its input to the output and to the load. This energy flow is provided by control of the switching process of one or more semiconductor devices. Based on converter application it is necessary to choose correct control algorithm for selected switching frequency of converter. Algorithm itself has to be utilized with s...

This paper presents a 0.35μm CMOS frequency to voltage converter for portable applications which is based on a operating principle comprises a differentiator, voltage to current converter, two RMS-DC converters, and a divider. Results show that the converter has a power consumption of 11.89mW operating at 3.3V supply voltage. This converter can accurately convert a sinusoidal signal frequency i...

In this paper, sliding mode control (SMC) for a bidirectional buck/boost DC-DC converter (BDC) with constant frequency in continuous conduction mode (CCM) is discussed. Since the converter is a high-order converter, the reduced-order sliding manifold is exploited. Because of right-half-plan zero (RHPZ) in the converter’s duty ratio to output voltage transfer function, sliding mode current...

I present measurements of the degree of second-order coherence g 2 0 for spontaneous parametric downconversion fields and discuss the differences between two-detector (unconditional) and three-detector (conditional) measurements of g 2 0 . An emphasis is placed on comparing measurements made using time-to-amplitude converters (TACs) to those made using a logic circuit, illustrating how the TAC ...

Stretch activation (SA) is critical to the flight ability of insects powered by asynchronous, indirect flight muscles (IFMs). An essential muscle protein component for SA and power generation is myosin. Which structural domains of myosin are significant for setting SA properties and power generation levels is poorly understood. We made use of the transgenic techniques and unique single muscle m...
