摘要
针对内燃机车司机室使用单相空调,设计研制了110V/220V变换用IGBT单相逆变电源。该电源由PWM高频升压斩波器及数字化控制SPWM逆变器组成,具有IGBT多重保护及机车抗EMI特殊设计。试验结果表明:该电源能长期可靠地为2.2kW单相空调供电,具有6kVA(500ms)瞬时起动功率容量。
For single phase air conditioner in diesel locomotive driver's cab,a IGBT inverter power supply is developed to convert 110 V DC into 220 V AC power.It consists of high frequency PWM boost chopper and digitalized SPWM inverter.It features IGBT multiple protection and special design for the protection of locomotive from EMI.Experiments show that the power supply can drive the rated 2.2 kW single phase air conditioner reliably for a long time,with a transient starting capacity of 6 kVA(500 ms).
