more attractive because it is characterized by being free, incur no fuel cost, abundant, limits less, distributed all over the world, pollution free, and require little maintenance. Maximizing power output from a solar system is desirable to increase efficiency and in order to maximize power output from the solar panels, one need to keep the panels aligned with the sun. As such, a means of tracking the sun is required. Efficient collection of maximum solar irradiance (MSI) on a flat plate type photovoltaic

American International University - Bangladesh Disadvantages of PWM Controlled Switching Devices in Converters The disadvantages of PWM controlled switching devices in converters are as follows: 1. The devices are turned “on” or “off” at the load current with a high di/dt value, 2. The it h 2 Th switches are subjected t a hi h lt bj t d to high-voltage stress, t 3. The switching power loss of a device increases linearly with the switching frequency. 4. The electromagnetic interference (EMI) is

1. A binary digit is called a bit. A computer system is sometimes subdivided into two functional entities: hardware and software. The hardware of the computer consists of all the electronic components and electromechanical devices that comprise the physical entity of the device. Computer software consists of the instructions and data that the computer manipulates to perform various data-processing tasks. Program A sequence of instructions for the computer is called a program. The data that are manipulated

* measure the input and output voltage and current of a common-emitter amplifier, * measure the phase-shift between the input and output voltages, * calculate the voltage, current, and power gains of a common-emitter amplifier, and * investigate the use of a BJT as a switch. THEORY The biasing of a transistor is purely a dc operation. The purpose of biasing is to establish a Q-point about which variations in current and voltage can occur in response to an ac input signal. In applications

all the time in audio. You may understand that 3 dB is considered a just noticeable change in volume level. But, you haven't a clue how to figure out how to figure out what 24 dBm from your mixing console means to your amplifier rated for 1.4V input sensitivity. You may be aware that dB calculations involve "logs" (logarithms). Thanks to a little technology, you can do dB calculations without knowing a thing about the mathematics of logs, anti-logs, ratios, exponents, or even much about math
