ব্যাখ্যা: UPS = Uninterruptible Power Supply

ব্যাখ্যা: The common base (CB) configuration is less than unity. The typical current pain of a cominon base amplifier is 0.98

ব্যাখ্যা: The commun ematter (CE) configuration is the most commonly used transistors. Common emilter transimer are used most widely, because a common emitter mansistor amplifier provides high current gain, high voltage gain and high power gain

ব্যাখ্যা: General purpose diodes are two terminal electronic components that allow current to flow in only one direction and is mainly used for power supply operation. Fast recovery diode is a semiconductor device which possesses short reverse recovery time for rectifications at high frequency.

ব‍্যাখ্যা: The primary element in a power electronic system it a switching power converter. The power converter consists of power semiconductor devices that are turned on and off at high frequencies the operation weitches the voltage and current through the devices delivering a control power at the output

ব‍্যাখ্যা: The common collector amplifier has a voltage gain of about I or unity gain

ব্যাখ্যা: A cycloconverter is a converter that converts AC voltage of one frequency to another frequency without an intermediate DC link. A cycloconverter also known as a cycloinverter or CCV or cycle converter.

ব্যাখ্যা: The electrical drive system is defined as the system which is used for controlling the speed, torque and direction of an electrical motor.

ব্যাখ্যা: Schottky also known as Schottky darrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action.

ব্যাখ্যা: An inverter refers to a power electronic device that converts power in DC from to AC form at the required frequency and voltage output Converters are electrical devices that covert the voltage from alternating current (AC) lo direct current (DC) A rectifier is a device that converts an oscillating neo-directional alternating current (AC) into a single-directional direct current (DC) An amplifier is an electronic device that increase the voltage, current or power of a signal.

ব্যাখ্যা: Transistor: Transistor is a semiconductor device. It's used to amplify and switch electrical signols and power Diode Diode is an electronic device with we transmitting terminals that allows electric current flow in one direction while blocking current to oposile direction

ব্যাখ্যা: Transducer: A transducer is an electronic device that converts energy from one from to another. Example: Microphones, thermometers, antenna etc. Transformer: A transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit. Amplifier: An amplifier is a circuit, which can be used to increase the amplitude of the input current or voltage at the output by means of energy drawn from an external source Oscillator: Oscillator convert direct from a power supply to an alternating current oscillating electronic signal, often a sine wave or a square wave and triangle wave.
