A constant-voltage and constant-current stimulus isolation unit.
When action potentials from a stimulated biological preparation are recorded i t is essential to isolate the stimulus resistively and capacitively from the ground in order to minimize stimulation artifacts. Such isolation can be achieved by using a transformer of special low-capacitance construction in the output of a stimulus generator (Donaldson 1958). The most widely used arrangement for the...
متن کاملA High Efficient, Compact 4th Order CLCL Converter Features to Use Constant-Current Power Supply
This paper presents a 4th order CLCL resonant converter which is suitable for constant current power supply applications. This converter is designed with Immittance characteristic with two inductors and two capacitors in resonant network. A detailed analysis and design process of a 200w converter as a constant current supply have been provided and simulation results are verified with results of...
متن کاملConstant Voltage Contact Surface
LIDAR (laser radar) is used to measure three-dimensional(3-D) object positions. It produces a range and an intensity image ofthe measured object and relieson the range image to determine the 3-Dpositions of the object. But, the range image is frequently corrupted withnoise. A dynamic calibration method has been established to improvethe LIDAR accuracy basedon a polyn...
متن کاملA parallel resonant constant current power supply
In the past, resonant converters have generally been analyzed and characterized for constant output voltage power supplies. When applied to power supplies, in which output current is regulated, the topological requirements of a resonant converter differ. This means, a resonant converter topology not suitable for constant voltage power supplies may become attractive for constant current power su...
متن کاملVoltage Flicker Recognition due to Electric Arc Furnaces via Wavelet Transform Applications
Electric Arc Furnaces (EAFs), widely used for steel production industries, are highly nonlinear time-variant disturbing loads because of the random change of the electric arc length results in arc voltage and furnace/supply current fluctuations. Consequently, Power Quality (PQ) problems such as undesirable variations of reactive power, poor power factor, harmonics, and voltage flickers may appe...
