【摘要】 变频空调压缩机为恒转矩负载。针对其调速要求,提出了一种基于FUJITSU单片机的全数字空间矢量PWM逆变器,使之在电网电压波动情况下输出转矩仍为恒定,并成功的应用于变频空调中,效果良好。更多还原

【Abstract】 The compressor of VF air-conditioner is a constant torque load. To control the speed, a kind of all-digital space-vector PWM inverter based on FUJITSU microprocessor is introduced. In the condition of voltage fluctuation, the output torque can still be constant. It has been successfully used in VF air-conditioner.更多还原
