13-October-2011 –Oztek Corp., a leader in developing and manufacturing technologically advanced inverter, DC/DC, and motor drive controls, introduces the OZSCR1100, a state of the art, digitally controlled, SCR control and firing board. The OZSCR11000 is a complementary product to Oztek’s standard OZSCR1000 controller, offering two functional differences; DC input bias power and low voltage AC line sensing. The OZSCR1100 operates off of 18V-32VDC input as opposed to universal AC voltage, and, in addition to the conventional SCR cathode line sense, provides three additional low voltage AC line synchronization inputs for systems where the AC mains voltage may not be present at the SCR cathodes during certain operating scenarios.
Like the OZSCR1000, the OZSCR1100 solves numerous SCR control and power system challenges, allowing fast and economical OEM product development. Systems operating from AC mains voltages up to 1000VAC are supported using the integrated, transformer isolated, “picket fence” firing circuitry. Dedicated high voltage and current measurement interfaces are provided to support closed loop digital control of both current and voltage. A digital PLL synchronizes to the AC line voltage, and can quickly report and respond to abnormal line conditions while intelligent fault handling minimizes down time and protects the system from damage. For complex systems requiring control of more than six SCRs multiple OZSCR1100 boards can easily be combined using the expansion interface.
“The OZSCR1100 expands upon our initial SCR control offering, addressing additional application requirements and demonstrating our commitment to the technology” said Dave Zendzian, Oztek CTO “Like the OZSCR1000, the OZSCR1100 is completely configurable using our SCC Tool, a Microsoft Windows graphical user interface (GUI), that provides a simple means to configure the products during installation, setup, operation, and trouble shooting.” Configuration, operating parameters, and pre-designed control algorithms can quickly be selected and configured using the PC based tool. With the ability to configure every system parameter, implementation possibilities are endless.

Oztek Corp. (www.oztekcorp.com), a leader in developing and manufacturing technologically advanced inverter, DC/DC, and motor drive controls, announced that it has received a $3 million, 150 unit order for Twin Drive units to be deployed in the ECOSaver IV hybrid electric buses manufactured by DesignLine International.
Oztek’s designed & manufactured Twin Drive Unit is comprised of a Traction Drive and a Brake Chopper. The Traction Drive inverter is responsible for converting DC power from the batteries to AC power for the main drive motors, which directly drive the wheels without a transmission or gearbox. The inverter is bi-directional, being able to provide power as well as absorb power during regeneration. The Brake Chopper is used to dissipate any excessive power that batteries are unable to absorb into an external brake resistor. The Brake Chopper can also regulate current to provide heat for the passenger compartment.
The Twin Drive Unit contains dual Traction Drive and the Brake Chopper assemblies within a single enclosure. This approach provides redundancy, allowing the bus the ability to still operate with reduced performance on a single unit (a limp home feature).
Since 1997 Oztek has been providing innovative power control solutions for use in Hybrid Vehicles and Traction Drives. Oztek continues to develop and build technologically advanced controls for demanding applications that also include, Fuel Cells, Utility Grid Tie, and Distributed Energy. Oztek’s unique advantage of resident multi disciplinary expertise enables them to develop unprecedented solutions to demanding engineering projects such as DesignLine’s ECOSaver IV.

PUBLICATION: New Hampshire Union Leader (Manchester, NH)
By MARK OUELLETTE Union Leader Correspondent
MERRIMACK -- At a time when manufacturing plants are struggling to make ends meet and, in some cases, shuttering their operations, OZTEK Corp. is thriving, especially after recently landing its biggest contract in the company's 12-year history.
OZTEK develops and manufactures electrical components, and received a $3 million, 150-unit order for its Twin Drive units to be installed in the ECOSaver IV hybrid electric buses made by North Carolina-based DesignLine International, according to Bob Mills, director of sales and marketing for OZTEK.
"We've been working with (DesignLine) for a couple of years in development, and originally started working with them when they operated out of New Zealand," he said. "The Twin Drive unit is a pretty complex piece of equipment and we built some prototypes, but now we're actually to the production stage." Delivery is just beginning for the first production models that are coming out of North Carolina.
During a recent tour of the 12,000-square-foot OZTEK facility at 11 Continental Boulevard, John Moisan, senior hardware director, said the Twin Drive unit consists of a traction drive inverter and a brake resistor.
"You're DC voltage is coming in from a large battery bank they have underneath the bus to provide the electric power, and there is an interface to drive the two motors and the brake resistors," he said. "The purpose of the brake resistors, in addition to being a heat source for the cabin that they can actively turn on, is they are also in the protective mode, so that it's a fully regenerative process.
"When the driver hits the brake of the bus, you get back EMF voltage drives, which actually works to charge your batteries and that's why they are so good in a city, stop-and-go environment," said Moisan. He added that the unit's redundancy allows the bus the ability to still operate with reduced performance on a single unit (a limp-home feature) if a field fault should occur.
Other OZTEK products include technologically advanced inverters and other motor drive controls for industry.
DesignLine, which has manufacturing plants in Charlotte, N.C., and New Zealand, makes coaches, buses, and specialty vehicles worldwide since 1985. OZTEK's parts are for the ECOSaver bus, which features improved gas mileage and lower emissions. DesignLine's customers include the New York Transit Authority and Disney, and they are talking with Chicago and Los Angeles transit authorities, according to Mills.
"It's so futuristic-looking that they did a big golf tournament in North Carolina and they had a whole series of buses to move people around, and no matter where this bus was in line, people would always get on this one first because it just looked cool," Mills said of the ECOSaver IV.
While some companies have struggled and had to lay off personnel, Mills said OZTEK is looking to hire more engineers to add to its 26 employees.
"Being involved in alternative energy sources -- wind power, solar power, hybrid vehicles -- those types of markets right now are extremely popular ... and well-funded because they produce real tangible results," he said. "Wind power, for instance, has gotten to be huge. It's huge in the rest of the world and now it's moved here and, again, it's all about managing power and that's what we do.
"We allow whatever the device is to create power and manage it so that you can do different things with it by putting it to a battery, a motor, and a grid," added Mills.
Mills estimated that the company could grow as much as 25 percent over last year's revenue figures.
