"Stiff Grid" and Parallel Operation AC Generator Excitation Regulator
SVRFP
The Kinetics model SVRFP Exciter/Regulator rectifier is designed and rated in capacity and operating parameters for the application of exciting the fields on an AC generator in parallel with other AC generators and the power system is a "stiff system" in relation to loading. A "stiff system" is a generating system that is of sufficient capacity or the generator is "small" in relation to the system grid, that the AC system voltage under impulse/step loading condition does not require forcing of the generator field to maintain the power grid voltage. Systems are designed with a standard unit service factor to operate within the +10% to -20% nominal voltage rating at 100% current rating.

Quasi Square Wave Constant Voltage Transformers
Osborne Quasi Square Wave Constant Voltage Transformers are used to regulate output voltages for applications that have varying input voltages. When used with a rectifier conversion circuit, these units provide an elegant design approach to voltage regulation. Osborne achieves this innovative approach by partnering the constant voltage transformer with an auxiliary resonant capacitor winding. The result is a unique (though time honored) technology that offers reliability, performance, and cost advantages over other styles of voltage regulation.

Schottky Mixer and Detector Diodes
Macom Technology Solutions Holdings Inc.
Schottky diodes are majority carrier diodes formed by plating a layer of metal on a layer of doped semiconductor, which forms a rectifying junction. The type of metal and the type of dopant in the semiconductor determines the diode’s barrier height, which is a measure of the amount of energy required to force the diode into forward conduction. MACOM produces Si Schottky diodes as well as GaAs Schottky diodes for use as signal detectors or in frequency mixers.

Roughness Tester
Compatible with four standards of site to measure surface roughness ofvarious machinery-processed parts, calculate corresponding and clearly display allmeasurement parameters. When measuring the roughness of a surface, the sensor is placed on the surface and then uniformly slides along the surface by driving the mechanism by the sharp built-in probe. This roughness causes displacement of the probe which results in change of inductive amount of induction coils so as to generate analogue signal, which is in proportion to the surface roughness at output end of phase-sensitive rectifier.
