Benefits of ReGen
能源再生的优势
•Braking energy converted to heat –
requires air conditioning•制动产生的能量将变为热能被消耗掉—需要空调
•VDC varies with Vline, increases motor
currents•变频器中间电压易受电网电压的干扰,增加电机电流
•Rectifier causes line distortion and
reduces power factor•普通整流器易造成电网波形失真,功率因数低
•Braking energy returned to line –
consumed by other appliances•制动产生的能量反馈电网供其他设备使用
•VDC independent of Vline, allows optimal
motor voltage w/ minimum motor
currents•变频器中间电压不易受输入电压的影响,优化电机电压,产生最小电机电流
•PWM converter achieves almost unity
power factor and can actually improve
line quality•PWM整流器具有功率因数高,提高电源的品质
