MTE Capacitors
MTE capacitors are high-quality power components used in a range of industrial and electrical applications, particularly in power quality, motor protection, and harmonic filtering. Known for their durability and reliability, MTE capacitors are often integrated into systems that include variable frequency drives (VFDs), AC motors, and power distribution equipment. They help mitigate voltage spikes, absorb transient energy, and smooth electrical waveforms, which improves system stability and extends the life of connected equipment. These capacitors are designed to handle demanding environments and meet rigorous performance standards.
In VFD applications, MTE capacitors are commonly found in filter assemblies such as dv/dt filters or sine wave filters. These filters work with the capacitors to reduce electrical noise and harmonics generated by switching operations within the drive. By reducing voltage rise times and filtering out unwanted frequencies, the capacitors contribute to reduced motor insulation stress, lower heat generation, and quieter motor operation. This results in better efficiency and fewer maintenance issues over time, especially in sensitive or mission-critical systems like HVAC, water treatment, or manufacturing processes.
Differences Between Power Supplies, Inverters and Transformers
Power Supplies and Power Quality
A power supply converts one type of power to another. The most common example is a power supply that takes AC voltage and converts it to DC voltage. While it is very common to use power supplies in industrial applications, one very common place to see a power supply used is for the devices such as: smartphones, laptops or tablets. Most devices come with a power cord that has a bulky block on the end of it. This block is where the power supply is located. Most devices do not use AC power, which is the type of power being supplied to homes. They use some form or DC power. The power supply changes the AC voltage to the correct DC voltage for the device.
Inverters
Inverters work in a similar way to power supplies, with one major difference, instead of converting AC power to DC power, the inverter does the opposite. It converts DC power to AC power. DC power is created by devices such as solar panels or batteries, but most homes require AC power. To convert the DC power that is generated by the solar panels, an inverter is used.
Transformers
Transformers convert one type of AC power to a different type of AC power. For example, homes commonly use 120 VAC and automatic sprinkling systems have valves that require 24 VAC. A transformer converts 120 VAC to 24 VAC so the sprinkler valves can operate properly. Transformers come in many different shapes and sizes. and can convert AC power up or down.
