In AC-DC-AC VVVF, We can accurately measure voltage, current, power and frequency with The HIOKI3164 and TOPVIEW31 analysis software, even if the wave is irregularities and distortion.
利用HIOKI3164和TOPVIEW31分析软件，可对交-直-交变频器中电压、电流、功率、频率进行准确测量，不论它是不规则波形还是畸变波形。
It can achieve a fixed output of DC voltage in the universal input range of ac 80 ~ 265 V. It owns the advantages of high efficiency, low total harmonic distortion, PF near to 1.
该方案能在80 ~ 265 V宽输入电压范围内得到稳定直流电压输出，具有效率高、总谐波畸变率低、功率因数接近为1等特点。
