Key Performance Indicators Direct AC-to-AC conversion matrix drive technology is unique to YASKAWA and provides a multitude of benefits unmatched by other low harmonic solutions.

Conventional Drive Topology Insulated Gate Bi-Polar Transistor (IGBT) Operation Convert AC to DC Convert DC to variable frequency AC Advantages Process control and energy savings Good displacement power factor Compact size Disadvantages Poor input harmonics Poor distortion power factor Conventional Drive L1 IM T3 T1 T2 L2 L3 Input Rectifiers DC Bus Output IGBTs More information on power factor later in the presentation.

Matrix IGBT Bi-directional Switch Circuit of Insulated Gate Bi- Polar Transistors (IGBT) and diodes Enables bi-directional switching between input phases Switching produces simulated sine wave output Enables regenerative power back to the supply The Matrix, however, uses bi-directional IGBTs in its design in a completely different configuration. Being bi-directional, they allow current to flow not only from the source to the motor, but also in the opposite direction, from the motor to the source. The next slide will show how these bi-directional switches are connected between the power input and the output to the motor in a “matrix” fashion.

~ M Matrix Drive Topology AC input to variable frequency AC output Nine bi-directional switches No DC bus Advantages Ultra-low input harmonics Near-unity true power factor Regenerative energy savings Smaller than other harmonic solutions Price Comparable to other low-harmonic solutions Higher than conventional six-pulse drives L1 T1 ~ L2 T2 M L3 T3 As you can see, the bi-directional switches enable the Matrix to connect each input phase to each output phase at any time. With no DC bus to charge, the charging current pulses are eliminated, thus virtually eliminating current harmonics. Since the Matrix drive produces ultra-low harmonics, the additional expensive and bulky components typically used for harmonics mitigation are unnecessary. The Matrix is a more expensive drive to build than a conventional drive, and so is priced higher. However, when compared to conventional drives with the harmonics mitigation components, such as multi-pulse transformers, the Matrix is priced comparably or lower.

Matrix Theory of Operation Line-side supply to the Matrix drive are the three input phase voltages The Matrix monitors the voltage difference between the phases Vmax Vmin The “brains” of the Matrix continually monitors and voltage difference between each of the phases and has those varying voltages to use for its pulse width modulation.

Matrix Principle of Control The difference between Vmax and Vmin Creates a virtual DC bus The maximum voltage differences, although not a constant DC, is utilized as a virtual DC bus.

Matrix Input and Output Voltages Input Phase Voltages Phase voltage differences Available at all times for Matrix operation Nine IGBTs can switch any input phase to any output phase at any time Matrix “knows” What voltages to use when for pulse width modulation for generation of three output phases Phase Voltage Differences The idea of the “knows” is how the Matrix uses the various voltage differences between the phases to select the right one at the right time to generate the pulses shown in the next slide.

Power Monitoring POWER OUTPUT U1000 iQpump can monitor power in several ways to give instant feedback on energy saved. POWER CONSUMPTION REGENERATIVE POWER POWER SAVED POWER BILL Power consumption, power output and regenerative power are internal kwh calculations that can be shown as monitors called up on the Z1000U screen. Power bill is a calculation of power consumption kwh multiplied by the $/kwh rate input by the user, again shown as a monitor. Power saved is a calculation like power bill, only based on the regenerative power value (not a comparison to any other drive or installation).
