Abstract	A new dynamic reactive power compensation technique for dynamic var compensator is presented. This paper presents the DC capacitor voltage control strategy, the loss current variation control algorithm and a new reactive current calculating method. And the desired compensating current is compared with the measurement of output current in the hysteretic current feedback-loop. Based on the analysis, a new- style dynamic var compensation control strategy is realized. It also analyzes the relationship between DC capacitor voltage variation characteristic and the active and reactive power flow between AC and DC sides. A novel dynamic var compensation prototype is developed. The experimental waveforms of the prototype show that this control algorithm has the expected compensating performance, demonstrating the validity of the design scheme proposed in this article.
