Using Source Measure Units to Characterize High-Power Semiconductors (Part 1)

The proliferation of electronic control and electronic power conversion into a variety of industries (e.g., energy generation, industrial motor drives and control, transportation, and IT) has made efficient power semiconductor device design and test more critical than ever. To demonstrate technology improvements, new device capabilities must be compared with those of existing devices. The use of semiconductor materials other than silicon demands the use of new processes. To be sustainable, these new processes must be tuned to deliver consistent results and high production yield. As new device designs are developed, reliability measurements must be performed on many devices over long periods. Therefore, test engineers must identify test equipment that is not only accurate, but scalable and cost-effective.

Motors Power NASA’s Interactive Humanoid Tour Guide

RoboThespian is a programmable, interactive humanoid robot designed to communicate, interact, and entertain. First developed in 2006 by Cornish company Engineered Arts, RoboThespian stands 5'9", with a full range of upper-body movement and human-like eyes. NASA will employ the robot’s third generation as a figurehead — meeting and greeting over 1.5 million visitors per year at its futuristic Cape Canaveral base.

Linear Actuators

Exlar, a business group of Curtiss-Wright Controls (Chanhassen, MN), offers the K Series™ linear actuators with a 75-mm frame size. They combine roller screw technology in varying performance levels, and allow the use of third-party motors. Along with 60-mm and 90-mm frame sizes, the actuators feature dimensions and form-factor consistent with ISO Metric pneumatic cylinder specifications for pneumatic and hydraulic replacement. They are compatible with any type and style of motor such as DC, stepper, and servo, and offer universal mounting configurations. They offer standard stroke lengths up to 48 inches. The standard body design provides an IP54S sealed housing with options available for IP65S sealing. A variety of materials and coatings is also offered, such as Type III hard coat anodizing, electroless nickel plating, and epoxy coating.

Motor Controller

Fairchild Semiconductor (San Jose, CA) has released the FCM8531 analog and digital integrated motor controller. The 3-phase, hybrid BLDC/PMSM controller offers two parallel processors — an advanced motor controller (AMC) and an embedded microcontroller (MCU) — that provide a one-chip solution for complex motor control applications. The two core processors exchange data through an internal communications interface.
