I2C bus digital potentiometer AD5242 was used as core of digital alternating current parameter multi-function meter, it has a point, two point and multiple point sampling arithmetic.
数字式工频交流电参数多用表以i2c总线数字式电位器ad5242为核心，其采样算法有一点、两点及多点。
A dynamic hysteresis-band current PWM control arithmetic is also designed to control the voltage of the DC bus, which keeps it steady effectively for the voltage of the neutral point of the DC bus.
设计了动态电流滞环pwm控制算法对直流侧电压进行控制，有效地保证了直流侧中点电位的平衡。
Therefore, a slack bus consideration of the current superposition arithmetic is superior to a slack bus consideration of the algorithm based on the sensitivity theory.
因此，考虑平衡节点的电流叠加法较考虑平衡节点的灵敏度算法更优越。
