| Abstract: | At present,SVPWM is widely used in various types of three-phase PWM inverter power supply such as UPS/EPS、frequency converter,for the advantage of high bus voltage utilization ratio、low switch wastage and so on.Because of the feature of the single-phase power supply,the technology is rarely used in single-phase inverter power supply.This article focuses on dsp implementation of single-phase SVPWM.Based on the research of space voltage vector,SVPWM has been applied in the Single-phase inverter,The method is used.By way of the disposal of zero voltage vector,SVPWM Optimal Switching method is successfully applied to 800W Automotive Inverter Power supply.The technology increased bus voltage utilization ratio and reduced switch wastage.The prototype has been manufactured in the lab,at the same time,the experimental results validated the effectiveness of this Single-phase SVPWM method. |
