In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light.[1] Opto-isolators prevent high voltages from affecting the system receiving the signal.  

Transistor Modules The transistor is the fundamental building block of modern electronic devices. An insulated-gate bipolar transistor (IGBT) is a three-terminal power semiconductor device primarily used as an electronic switch which, as it was developed, came to combine high efficiency and fast switching. It switches electric power in many modern appliances: variable-frequency drives (VFDs), electric cars, trains, variable speed refrigerators, lamp ballasts, air-conditioners and even stereo systems with switching amplifiers.

The IGBT combines the simple gate-drive characteristics of MOSFETs with the high-current and low-saturation-voltage capability of bipolar transistors. The IGBT combines an isolated-gate FET for the control input and a bipolar power transistor as a switch in a single device. The IGBT is used in medium- to high-power applications like switched-mode power supplies, traction motor control and induction heating. Large IGBT modules typically consist of many devices in parallel and can have very high current-handling capabilities in the order of hundreds of amperes with blocking voltages of 6000 V. These IGBTs can control loads of hundreds of kilowatts.

Electronic Components like axial fan, drive module, diode module, etc.These components are tested on various qualitative parameters under the charge of deft technocrats in order to meet international quality norms. These components are widely used in electronics industry to be installed in PWM, UPS, SMPS and other power circuits to increase their efficiency.

Dynamic Braking Resistors – Standard and Custom BuiltDuring dynamic braking, the traction motors, which are now acting as generators, are connected to braking grids of large resistors which limit the current flow and dissipate the converted energy as heat in the resistors instead of the motor.

In electronics, a diode is a two-terminal electronic component that conducts primarily in one direction (asymmetricconductance); it has low (ideally zero) resistance to the flow of current in one direction, and high (ideally infinite) resistance in the other.  

Electronic  Components generate the most heat in your typical system. It’s also the most temperature-sensitive. That’s why fans are necessary to aid in cooling the system. Without them, machines would overheat and cease functioning. The power supply also increases the temperature of a system. So although the components generate the most heat, the power supply also makes it necessary to have a cooling system in place to keep temperatures low and keep it from overheating. Without a way to maintain its temperature, a system won’t last.  

A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to store electrical energy temporarily in an electric field. The forms of practical capacitors vary widely, but all contain at least two electrical conductors (plates) separated by a dielectric (i.e. an insulator that can store energy by becoming polarized). The conductors can be thin films, foils or sintered beads of metal or conductive electrolyte, etc. The nonconducting dielectric acts to increase the capacitor’s charge capacity.  

For conversion of an Alternating Current (AC) input into a direct current (DC) output known as Bridge Rectifier. A Bridge Rectifier provides full wave rectification from a two wire AC input resulting in lower cost and weight as compared to a rectifier with a 3 wire input from a transforer with a centre tapped secondary winding.
