ADC0804 Family

ADC0804 Family: The ADC0804 Family are ADC0803, ADC0804 and ADC0805 are CMOS 8-bit successive-approximation analog to digital converters. These devices are design to operate from common microprocessor control buses, with tri-state output latches driving the data bus, and are identical except for accuracy. Pin Diagram of ADC0804 Family: Fig. 14.120 shows the pin diagram of […]

Different Types of DC Distributors

Different Types of DC Distributors: Different Types of DC Distributors – In the beginning of the electrical age, electricity was generated as a direct current and voltages were low. The resistance losses in the lines made it impracticable to transmit and distribute power for more than a few localities of the city. With the development

DC Distribution System

DC Distribution System: It is a common knowledge that electric power is almost exclusively generated, transmitted and dis­tributed as a.c. However, for certain applications, d.c. supply is absolutely necessary. For instance, d.c. supply is required for the operation of variable speed machinery (i.e., d.c. motors), for electro­chemical work and for congested areas where storage battery

Control of DC Drives Using Microprocessors

Control of DC Drives Using Microprocessors: The dc motors fed from thyristor converters for variable speeds are being ex­tensively used in general industrial applications. A dual converter, which is a combination of two antiparallel connected three phase/single phase bridge converters, provides a reversible Control of DC Drives Using Microprocessors with regenerative facilities. The re­sponse of

Chopper Fed DC Drives

Chopper Fed DC Drives: The variable voltage to the armature of a dc motor for speed control can be obtained from a dc chopper which is a single stage dc to dc conversion device. The voltage variation at the load terminals can be obtained by using either current limit control or time ratio control. In
