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
