The principle of hybrid active power compensation technology is analyzed and the analytical method of hybrid active compensation and conventional shunt active power filter in the aspect of DC capacitor voltage and device capacity are proposed. The analysis shows that hybrid active compensation has the outstanding advantages of low DC-side capacitor voltage and much smaller inverter capacity than that of conventional active power inverter when the same capacity load is compensated. The results of computer simulation of the two agree well with the theoretical ones. Finally, the experimental results of a 50 kVA prototype are given, and the hybrid active power compensation technique is verified to have good compensation characteristics
