VYCON’s VDC Direct Connect UPS backup systems bring unprecedented power capacity for instantaneous and reliable backup power for today’s mission-critical applications. Data centers, hospitals, broadcast studios, casino gaming centers and manufacturing plants are enjoying the reliability benefits of VYCON’s flywheel energy storage systems. Utilizing clean energy storage from VYCON’s patented flywheel technology, the VDC, VDC-XE and VDC-XXE are the perfect solutions for users needing a more reliable and greener approach to backup power in place of hazardous lead acid based batteries. Compatible with the Liebert brand of three-phase UPSs utilizing a systems interface with the DC bus of the UPS just like a bank of batteries, receiving charging current from the UPS and providing DC current to the UPS inverter during discharge.
The VDC energy storage systems hold kinetic energy in the form of a rotating mass, and convert this energy to electric power through patented technology within the flywheel system. Our unique technology includes a high-speed motor generator, active magnetic bearings that are used to levitate and sustain the rotor during operation, and a superior control system that can provide information on the system performance. These innovative technologies enable the VYCON flywheel to charge and discharge at high rates for countless cycles making conventional technologies like batteries obsolete.
Advantages of Flywheels
Flywheels are a reliable, clean and efficient alternative energy source. In comparison to lead acid batteries, flywheels offer an innumerable amount of benefits.
First, they eliminate the batteries inevitable flaw of failure. Batteries generate heat, and heat reduces battery life. Lead-acid batter¬ies degrade every time they are cycled (used) and one bad cell in the battery bank can take out the others, rendering equipment useless. Moreover, batteries take up a lot of space, require expensive cooling and contain haz¬ardous chemicals, making disposal an issue. Flywheels eliminate constant battery replacements, which are needed every 2-3 years. The VYCON® patented technology design requires little maintenance and allows for a 20 year life-span.
The VYCON energy storage systems have a small footprint in comparison to batteries, and produce no emissions or carbon dioxide. The VYCON product line is ideal for consumers who have limited space and enables equipment to be used in spaces not typically thought of for electrical equipment.
Top data centers, hospitals and manufacturing plants trust VYCON energy storage systems to keep their facilities up and running 24/7.
Other advantages of the VYCON energy storage systems include:
- Reliability– Up to 20x higher reliability than a single string of Valve Regulated Lead Acid (VRLA) batteries that are typically used in UPS applications
- Longer Life– Flywheels have a longer life than VRLA batteries and last 10 times longer (the VYCON energy storage system has a 20 year life and run performance)
- Reduction of Required Maintenance– VYCON units require little maintenance as it utilizes a 100% magnetic levitation system rather than mechanical bearings as other suppliers
- Footprint Savings– VYCON units save space that would be taken up by an equivalent power rated battery bank. This lowers construction costs or allows space to be freed up to use more efficiently.
- Environmentally Friendly– VYCON units produce no carbon dioxide or emissions.
- Lower-Life-Cycle-Costs– The ROI is typically within 3-4 years, and over a 15-20 year operation, the VYCON energy storage system’s total life-cycle is a fraction in comparison to batteries.
- Does not require a temperature controlled environment– VYCON units can be operated in extreme temperatures ranging from -4⁰F to 104⁰F (-20⁰C to 40⁰C)
Vycon Direct Connect XE
The VYCON® Direct Connect (VDC®) XE generates 300kW of power using patented flywheel technology. It is officially certified and tested by all major Uninterruptible Power Supply (UPS) manufacturers and is supported by a network of over 200 trained technicians on a 24 x 7 basis.
Vycon VDC XXE
The VYCON® Direct Connect (VDC®) XXE generates 300kW of power using patented flywheel technology. It is officially certified and tested by all major Uninterruptible Power Supply (UPS) manufacturers and is supported by a network of over 200 trained technicians on a 24 x 7 basis.
The successful integration of patented high-speed motor, generator and magnetic bearing technologies gives VYCON a substantial edge in delivering the four components that combine for a highly efficient, extremely reliable flywheel system. Four components—the high-strength steel hub, the dual mode motor/generator, the fully active magnetic bearings, and the sophisticated system controls—constitute a unique synthesis of proprietary technologies.
VYCON was formed in 2002 as a wholly owned subsidiary of Calnetix Inc., and subsequently spun-off in 2003 to allow the company to focus on its product line and acquire funding to support this focused effort. Calnetix licensed its patents and assigned, licensed or sublicensed certain rights to VYCON in inventions, technology, trade secrets, know-how, proprietary processes, copyrights, certain other patents, and other intellectual property. The rights granted to VYCON are confined to the specific field of use, where Calnetix granted VYCON a fully paid-up, royalty free, irrevocable, worldwide, exclusive license in and to Calnetix motor generator and magnetic bearing technology and patents in the field of energy storage flywheels for terrestrial use.
Smart Monitoring System
VDC energy storage systems feature a user-friendly touch screen interface as the primary means for the operator to monitor and control the system. The touch screen interface displays an assortment of information, including system information, system status, system errors, operating parameters and event log menus. The control panel is designed to provide the user with graphical description of the flywheel storage in real time. The screen provides rotor speed, change capacity, discharge event history, adjustable voltage –settings, RS-232/485 interface, alarm status contacts, soft-start pre-charge from DC bus and push-button shutdown. The “Service GUI” contains the interface for multiple trouble-shooting, calibration and set-up capabilities.
High-Speed Permanent Magnet Motor Generator
The VDC systems’ motor generator design utilizes specialized rare earth magnets to minimize rotor heating and maximize efficiency and reliability. This type of motor design allows the system to cycle quickly without overheating and can therefore be used in difficult applications with high cycling and long life requirements. The motor generator is rotated at speeds up to 36,750 RPM, where the flywheel system is at a fully charged state. During discharge, the rotor speed decreases to a minimum speed, typically 10,000-12,000 RPM. This speed range is called the discharge range and can be adjusted for more energy or higher cycling depending on the application. The rotor assembly of the flywheel operates in a vacuum provided by an external pump. By removing air from the rotating area of the motor, all windage losses from the system are eliminated, increasing electrical efficiency.
Bi-Directional Power Converter
The power module is an Insulated Gat Bipolar Transistor based bi-directional direct current (DC) to alternating current (AC) or AC to DC device. During the charging or motoring state, it acts like Uninterruptible Power Source (UPS) inverter, and the power module converts DC from the UPS to 3-phase AC that is applied to the stator and spins the flywheel. While it is discharging or generating, it acts like a UPS rectifier; the power module converts the 3-phase AC from the flywheel motor-generator to a regulated DC.
