In this paper implementation of All digital PID controller using Field Programmable Gate array (FPGA) is presented. Nowadays embedded control applications requires low power and fast acting PID controllers with a closed loop performance using less resources, resulting in cost reduction. In digital PID controller error signal is generated by using comparator which is analog in nature. By using A...

In arithmetic circuits for digital signal processing, radixes other than two are often used to make circuits faster. In such cases, radix converters are necessary. However, in general, radix converters tend to be complex. This paper considers design methods for p-nary to binary converters. First, it considers Look-Up Table (LUT) cascade realizations. Then, it introduces a new design technique c...

Current-mode control (CMC) is an extremely popular dc-dc converter loop architecture—and with good reason. Simple operation and dynamics are achieved even though two loops, a wide-bandwidth current loop lurking inside an outer voltage loop, are required. Peak, valley, average, hysteretic, constant on-time, constant offtime, and emulated current-mode are commonly used. Each technique offers plus...

In educational as well as research environments there is a demand for an easy way to prototype switching converters. Several recurring standard tasks like pulse pattern generation, driving controllable switches and analog to digital conversion of physical quantities e.g. current, voltage and temperature, need to be performed. Because these standard tasks interfere with the research focus, a mod...

ACKNOWLEDGMENT I rarely get an opportunity to formally acknowledge those who have put me on this path. That being the case, I would like to take the opportunity to thank my parents. My father , Harvey Gray, gave me the analytical eye I cherish so much while my mother, Leslie Simmons, showed me how to use it. It is interesting, I suppose, that the only place their marriage ever made sense was wi...

Floating-gate analog circuits are being used to implement advanced signal processing functions and are very useful for processing analog signals prior to analog to digital conversion. We present an architecture analogous to FPGA architectures for rapid prototyping of analog signal processing systems. These systems go beyond simple programmable amplifiers and filters to include programmable and ...

A synthesiser has been designed for polyphonic (multivoice) singing synthesis. Singing synthesis requires frequent updating of parameters to achieve a natural output sound. These parameters include fundamental frequency, formant frequencies, formant bandwidths, and voice source parameters (such as Open Quotient). The synthesis engine is controlled using a script and a graphical user interface. ...

This paper presents a grid connected photovoltaic system, which acts as both power generator and active power filter (APF), based on Flying Capacitor Multicell (FCM) converter. Increase in the number of output voltage levels, natural self-balancing of flying capacitors and dc link voltage and lower power rating of components are the main futures of FCM converter compared with conventional multi...
