In motor control circuits, a diode known as the freewheeling diode is connected across motor terminals to allow for dissipation of energy stored in motor inductance and to provide for continuity of motor current when the SCRs are blocked. It also provides protection against transient over voltages. Freewheeling Diode in Controlled Rectifier Energy Stored in […]

Characteristics of PN junction diode is a graph between the voltage applied across its terminals and the current that flows through it. It is drawn to know the behavior of diode in the electrical circuit. For a typical junction diode, characteristics are shown in Figure. It shows how much current will flow for a particular

Zener diode is a crystal diode having unusual reverse current characteristics which are particularly suitable for voltage regulating purposes. When a reverse voltage applied to a zener diode is increased, a value is reached at which the current increases greatly from its normal reverse value.   This voltage is known as zener voltage (Vz) or

Hi friends, in this article, I am going to describe the working principle of rectifier, if you are interested, keep reading. Electric energy is available in homes and industries in the form of alternating voltage. But for the operation of most of the devices in electronic equipment, a DC voltage is required. Therefore almost all

Different types of capacitors are found nearly in every electronic circuit. A capacitor is basically mean to store electrons (electrical energy) and release them whenever desired. A capacitor consists of two conductors separated by an insulator. The conductors are known as plates and the insulator is known as a dielectric.     Capacitance is the
