Breakthrough Technology:
OCC-Power Factor Corrected Rectifier leverages unique patented technology invented at Caltech & University of California and developed by the world leading power electronic experts under the partial sponsorship of U.S. Department of Energy. OCC-PFC is the first hardware-enabled 3-phase PFC rectifier with high reliability, ultrafast dynamics, and simple user interface, enabling AC/DC conversion with regulated DC bus and unity power factor.

• Diode rectifier front-ends do not meet power quality regulation
• Equipment with diode rectifier sensitive to grid voltage fluctuation
• Facility transformer overloaded

OCC Solution:
• Correct the power factor to unity with low harmonics
• Stable DC bus during grid voltage fluctuation
• Reduce facility transformer loading

OCC Applications:
• PFC front-end for motor drives
• PFC front-end for UPS
• PFC front-end for medical/industrial equipment
• Data center high voltage DC power supply
• Semiconductor foundry power supply with unity
power factor
• Electronic AC load with dynamically adjustable
inductive/capacitive impedance and energy
regeneration capability
• Microturbine power generation rectifier
• Wind power generation rectifier
• Microhydro power generation rectifier
