TMEIC TMdrive®-30 Medium Voltage 3-Level IGBT System Drive

TMdrive-30 is a totally digital- and vector-controlled sine wave PWM inverter that performs highly precise and

efficient variable speed control of AC motors with a small to medium capacity. Also, TMdrive-P30 is an IGBT

converter that receives the AC power supply and converts it into the DC power for the IGBT inverter. This

equipment is power supply system-friendly because it controls the input current as sin wave. Before starting

Specifications of TMdrive-30 and TMdrive-P30

Features

(1) High performance and high reliability

Use of a large capacity IGBT improves the reliability, reduces the switching loss, and improves the control

performance. The control circuit uses a newly developed power electronics equipment control processor

PP7 and an eight-layered surface mounting circuit board, ensuring high component integration and high

reliability.

(2) Highly precise speed control (TMdrive-30)

Use of totally digital and vector control ensures highly precise speed control and high speed response.

(ωc = 60 rad/s, ωc = 20 rad/s for speed sensor-less control)

(3) Transient response and stability

Use of totally digital and vector control makes it possible to ensure stable operation characteristics

including the transient status.

(4) Quadrantal operation (TMdrive-30)

Quadrantal operation, normal, reverse, power running, and regenerative operations are made smoothly.

(Note: This feature applies only when the reverse-parallel thyristor converter (TMdrive-T30) or IGBT

converter (TMdrive-P30) is used.)

(5) Supporting various speed sensors (TMdrive-30)

Drives a squirrel-cage induction motor. A pulse generator or high-resolution brushless resolver can be

used as a speed detector installed in the motor. Speed sensor-less vector control is also possible.

(6) High power factor (TMdrive-P30), high efficiency

A high efficiency drive system can be constructed due to high efficiency achieved by sine wave PWM

control and small device loss. Because TMdrive-P30 can control the power waveform as sine wave, it

reduces power supply higher harmonic waves and can control the power supply factor as high as 1.

(7) Energy saving

With combined with a common converter (TMdrive-P30. TMdrive-T30 (reverse-parallel type)) having

power regeneration function, the energy is saved in applications where continuous regenerative operation

is made, or the acceleration and deceleration are made repeatedly.

The regenerative energy is stored as DC voltage and used to drive other inverters. Additionally, the power

is regenerated to the AC power supply by the common converter with the power regeneration function.

(8) Maintenance tool (optional test and adjustment support tool)

Not only as a maintenance, monitoring, and fault analysis tool, this tool can also be used as an adjustment

tool. To change the parameters and collect traceback data, this tool is required.

(9) Main unit (PC) transmission

Transmission via Toshiba integrated controller (V series) and TOSLINE-S20 can be performed. This

equipment also supports open transmission such as ISBus, Profibus, and DeviceNet (optional).
