3 Phase Inverter using Arduino:- Build your own and simple 3 phase low watts square wave inverter. The 3-phase inverter circuit using Arduino and MOSFET. Here iam using single phase transformer 3 number per phase. Required Components:- 1. Resistor 4.7k = 3 Nos. 2. BC557 Transistor =
An inverter circuit is used to convert the DC power to AC power. Inverters can be of two types True/pure sine wave inverters and quasi or modified inverters. These true /pure sine wave inverters are costly ,while modified or quasi inverters are inexpensive. These modified inverters produce
TRIACs: A triac is a bidirectional, three-terminal dual, back-to-back connected (SCR) switch. This device will conduct current in both directions when a small current is constantly applied to the Gate. If the gate is given a small, brief, current during any instant of a cycle, it will
SCR-SILICON CONTROLLED RECTIFIER The SCR-Silicon Controlled Rectifier is a semiconductor device that is a member of a family of Thyristors. It is a 3-leaded device and when a small current enters the Gate, the thyristor turns on, and stays on. It only conducts current between Anode and
MOSFET means Metal Oxide Semiconductor Field Effect Transistor. FETs operate exactly the same as a normal transistor except they have different names for the input and output leads and the voltage between the gate and the source has to between 2v to 5v for the device to
DC motor (BO) Battery Operation. Dc motor converts electrical energy into mechanical energy. Why DC gear motor used in robot Motor control circuit. DC MOTOR concept is where gears reduce the speed of the vehicle but increase its torque is known as gear reduction. In DC motor
SENSOR: The sensor is a transducer type, it is used to sense or detect events or changes in physical quantities and gives a corresponding analog output. TYPES OF SENSOR: 1. IR sensor. 2. proximity sensor. 3. Temperature sensor. 4. Pressure sensor. 5. Light sensor. 6. Fires sensor.
