In conclusion, increased serum glucose levels and glucose metabolism induced by a single 60-Hz EMF exposure were closely related to the cellular redox state and the insulin/glucagon ratio. Whenever electrical current flows, both electrical and magnetic fields are generated, which are known as ...
Basic motor and soft start theory Introduction A solid-state soft start controller or starter controls the starting torque and current of an AC motor electronically. They can be used in almost any application such as: • Commercial—HVAC fans and pumps •...
In 1820, Andre-Marie Ampere identified that the existence of a magnetic field is related to the flow of electricity through a closed conductive contour, while the same year Jean-Baptiste Biot and Félix Savart arrived at an equation that determines the magnetic field strength in the vicinity of...
The spring constant k of these polyimide sheets can then be calculated based on their dimensions and material properties using equation (1). k=E·W·T34·L3(1) E denotes the encapsulating polymer's Young's modulus, W, T and L the width, thickness and length of the sheets respectively. ...
The output voltage of the circuit of FIG. 5 is given by the following equation: ##EQU1## The resistor values shown in FIG. 5 may be used for a system with 120 v RMS line to neutral. If the solid state switch is open, VB=0 and Vomay be calculated to be 12 v peak. If the ...
A disk drive is disclosed comprising a disk comprising tracks defined by servo sectors, a head, and control circuitry comprising a servo control system operable to actuate the head over the disk based on the servo sectors. An estimated acceleration EstAccel of the head over the disk is generate...

An equation describing this relationship can be derived from the equivalent circuit shown in Figure 6. It considers the reflection of the voltages V1 and V2 and resistances R1 and R2 to the intermediate (inductor) segment of the converter, using the principle of DC-transformer and the duty ...
Keywords: solid state transformer; microgridvoltage balancing control; decentralized control; real time simulation 1. Introduction The electricity consumption growth and environmental concerns favor the proliferation of renewable sources and distributed generation (DG) integration into the grid [1]. This ...
Introduction The utility of induction motors has risen considerably owing to its integration with power electronic converters, which made variable frequency operation realizable. This, in turn, made the induction motor the workhorse of the industry. Of all the variable frequency control strategies, the...
