Fuji Electric FRENIC MEGA G2 Series - 11.10 Compact Power Regeneration PWM Converter

11.10 Compact Power Regeneration PWM Converter
11-48
11.10 Compact Power Regeneration PWM Converter
This is a more compact, lightweight product than the RHC series in section 11.9, and similarly, to convert power
supply side current to a sine wave with PWM control in order to significantly reduce harmonic current, conversion
factor Ki in the "Guideline for Suppressing Harmonics by Customers Receiving High Voltage or Special High Voltage”
issued by the Agency for Natural Resources and Energy in the Ministry of Economy, Trade and Industry can be
handled as “0” (in other words, zero harmonics are produced.)

*1 When the power supply voltage is 210 V or 420 V or higher, and the operating load is 50% or higher, the power
factor for the power supply drops to approximately 0.95
(only during regenerative operation).
