Abstract:

We build a simple and inexpensive three digit display. It's a voltmeter module but it has also general purpose digital IO pins. You could use it as well to read a digital sensor and display the value. It can be freely programmed, calibrated and even be programmed with a non linear formula. It's a display where you can define the relation between the measured value and the displayed number. The ICL7107 is a high performance, low power, 3.5 digit analog to digital converter. The IC includes internal circuitry for seven segment decoders ....etc

Abstract.
Using piezoelectric elements to harvest energy from ambient vibrations has been of great interest over the past few years. Due to the relatively low power output of piezoelectric materials, energy storage devices are used to accumulate harvested energy for intermittent use. Piezoelectric energy harvesting circuits have two schemes: one-stage and two-stage energy harvesting. A one-stage energy harvesting scheme includes a conventional diode bridge rectifier and an energy storage device. In recent years, two-stage energy harvesting ci ....etc

Introduction to Belt drives



Typical belt drives

Two types of belt drives, an open belt drive, (Fig. 13.1.1) and a crossed belt drive (Fig. 13.1.2) are shown. In both the drives, a belt is wrapped around the pulleys. Let us consider the smaller pulley to be the driving pulley. This pulley will transmit motion to the belt and the motion of the belt in turn will give a rotation to the larger driven pulley. In open belt drive system the rotation of both the pulleys is in the same direction, whereas, for cross ....etc

In electronic ac voltme ters input signal is firstly rectified and then sup plied to the dc amplifier. In some circuits, the block diagram includes the attenuator, the rectifier and the multi-stage DC amplifier. and finally the output is shown in the PMMC meter. Sometimes, the block diagram will be attenuator->multistage amplifier, rectifier and PMMC meter.

AC voltmeters are divided into:
Average Reading AC Voltmeters.
They are average responding type and indicates the average value of the voltage on the dial. This method is ef ....etc

CHAIN DRIVES IN LOW TORQUE DRIVES AND REDUCING PULSATIONS
INTRODUCTION TO DRIVES

Mechanical components used for power transmission. It may be belt, chain or gear depending on engine design parameters like - Distance between crankshaft and camshaft, engine maximum speed, engine-torque and engine construction cost. - Power transmission is done from one shaft to another shaft which may or may not rotate at same speed.

difference between chopper fed drives and converter fed drives pdf

If the source of supply is d.c. (for example in a battery vehicle or a rapid transit system) a chopper-type converter is usually employed. The basic operation of a single-switch chopper was discussed in topic 2, where it was shown that the average output voltage could be varied by periodically switching the battery voltage on and of for varying intervals. The principal difference between the thyristor-controlled rectifier and the chopper is that in the former the motor current ....etc

BACKGROUND

The significance of power factor (PF) correction is reflected in the large number of documents addressing this subject, in the engineering design effort, and in the numerous industrial plants that manufacture equipment for the control of reactive power and filtering of current harmonics . Some of the benefits derived from correct PF adjustment are:
1. reduced energy loss;
2. released generation, transmission, distribution, and substation capa ....etc
