All industries need a power supply

Industrial drives are used to control this power. They are also known as inverters. Power drives are essential to all modern industries across the globe. Most drives control fans, pumps, and compressors.

Drives control the speed of a motor by varying the frequency and voltage of the power supply. This control reduces energy usage and optimises the operation of devices. They can also control the ramp-up and ramp-down of a motor during start or stop that reduces mechanical stress on devices.

Inverters can convert energy from sustainable sources like sun, wind, or tide and transfer it to the electrical network for local use.


An inverter is an electronic device that changes direct current (DC) to alternating current (AC). Different devices will produce varying AC frequencies. In contrast, converters change AC to DC.

Each particular device produces a different input voltage, output voltage, and frequency. The power is given by the DC source as the inverter does not produce power itself.

Inverters are used in electrical power applications where high currents and voltages are needed. Contrastingly, electronic signals provide low currents and voltages and are controlled by oscillators. In addition, rectifiers convert AC to DC.

Inverters use one of two designs to produce power from low-voltage DC sources:

  • Switching boost converter to produce high voltage DC and then converting it to AC
  • Converting DC to AC battery level and employing a line frequency converter to make the output voltage

An unregulated power supply is used for environments where high reliability, low cost, and high current are necessary. They are a sound option for inductive uses that don’t require tight regulation of the output voltage or waveforms like dc motors, indicator lamps, solenoids, and relays. Although the unregulated power supplies are tough, many industries use linear or switching power supplies.

The linear power supply was once the norm many years ago but even today there are uses for it. If the device needs a large inrush current, like starting a dc motor, the large transformers, full-wave rectifiers, large capacitors, and regulators found in the linear supplies will function well. The linear power supply is also considered a clean dc voltage source with low output voltage ripple and noise. Despite the linear power supply’s benefits and cheap cost, the size, weight, and inefficiency mean it is a poor choice in industrial power supply applications. The switching power supply is a better option.

The switching power supply is the most common power supply for industrial applications in the modern era. It is more complicated electronically, converting the ac input voltage into high-frequency, low-voltage dc, but it’s smaller and more efficient. Most switching power supplies are only a quarter of the size of an equivalent linear supply, and they are 25% more efficient. This makes the switching power supply the premier choice for most industrial applications.
