The matrix inverter is also known as the inverter that directly converts the AC input voltage to the AC output voltage.

In 2006, Yaskawa first introduced the world’s first matrix conversion control method, which helped this control method completely overcome the disadvantages of the traditional AC inverter series. The breakthrough development of this technology gave birth to the U1000 series of inverters.

This state-of-the-art motor-driven inverter is only available in Yaskawa and eliminates the problems of standard AC inverters.

With traditional technology, the input AC power is rectified to DC and then reversed back to the output AC source. This process generates harmonic currents that cause large losses and interfere with the system. At the same time, in the process of braking kinetic energy, it is necessary to have an additional discharger to the grid or a discharge resistor to burn off excess electricity.

With these distinctive features, when using the U1000 inverter, it helps to reduce the cost of external equipment. No braking unit, no input or output filter needed. This reduces costs and improves engine life.

The U1000 ranks first in the performance of the general-purpose inverters, further improving your facilities.

A matrix converter is an AC/AC converter consisting of 9 bidirectional switches arranged in a matrix. It converts three-phase AC power directly from the required voltage and frequency.

(reuse previously wasted electrical energy with a new way to save electricity)

When a motor rotates it consumes energy, when a motor is pulled it produces energy.

We can save electrical energy by taking advantage of this renewable energy source instead of wasting it.

You can save huge amount of energy

Use analog or communication signals to monitor energy saving processes

With no surrounding equipment affecting, the input waveform is in sinusoidal form, similar to a commercial power supply, so harmonics will be improved for surrounding machinery.

The capacity of the electrical system is increased, and the harmonic regulations are also met.

Comparison between AC inverter without REACTOR filter, inverter with REACTOR filter and inverter that matches U1000.

The power factor is high so you can choose a lower power supply capacity.

You can shrink the conductor size, reduce the generator power. And Don’t worry about being fined because of harmonic problems
