Some of us, who have the opportunity of having frequent acquaintance with electric machineries like power tools, know the importance of non-isolated power supply in every machine we use.
We have also heard about inductors and transformers.
Transformers are used to transfer electrical flow from one circuit to another, and inductors are used to control power supply in machines.
According to the experts, non-isolated power supply devices help inductors to increase or decrease the voltage ratio in the machine circuit board.
That is their primary work, but that does not conclude their gift to the machine industry.
These devices have the capability to reduce noise of machines and they are affordable too.
Now let us talk about a few popular isolated power supply converters.
Boost converter This converter is designed to transmit an increased level of output dc voltage than the level of input dc voltage.
It falls under the class of SMPS.
When a machine is 'turned on', and electricity flows through the inductor, these devices store the energy within.
After the machine is off, the energy stored inside changes its polarity.
That is how the boost converter works.
Buck converter Reducing voltage flow in the machine is this converter's forte.
Flywheel diode, Switching power, inductor, and output filter capacitor are this converter's main circuit components.
This device saves the machine from high flow of electricity.
Cuk converter A CUK converter is very popular among all the non-isolated power supply systems.
This device is designed to increase and decrease electricity flow in the machine circuit.
It has a voltage capacitor and an inductor that helps it to keep voltage level in line.
Its voltage output has an inverted polarity the same as few other converters.
Charge-pump converter This voltage-converting device is used in low powered applications.
This device has the capability to store energy within the capacitors, while other converters store electricity in magnetic field created by inductors.
We are all aware that, inductors are responsible for increase or decrease of the voltage flow.
But, the converters help inductors to complete their work with ease.
Non-isolated power devices have gained much importance in past few years.
Engineers suggest to select a voltage converting device that suits the machine you are about to buy.
It is important to check circuit breakers, surge suppressors, fuses and safety switches of a machine and be assured of its quality and genuineness.
Checking its non-isolated power supply devices reduces the chances of sudden disruption of machine's health.
