Check the latest article of Nasir (one of our members) from his tutorial about inverters.

Owing to the recent popularity and immense industrial usage of multilevel inverters, a lot of research is going on in the field of multilevel inverter topologies. All these topologies have various applications along with their inherent limitations.

There are two methods of controlling multilevel inverters:

  • PWM Control (allows variations in output voltage)
  • Line Frequency Control (does not allow variation in output voltage)

Three of the very basic and might I say the initial topologies are:

Choosing the right power supply 1

From the domestic user point of view, choosing an appropriate power supply is important. It is your insurance strategy against power surges and also prolongs the equipment of the device attached to. This post would illustrate on the types and draw a comparative analysis, helping you to make a reasonable choice.

The regulated power supply indicates to a power supply that can supply variable output voltages that are helpful for testing circuits. Nearly all devices that we use in circuits require a dc source.

The basic construct of the power supply involves a power supply and a voltage regulating device. The significant types of power supplies have been discussed below:
