注意，用这种方法计算电阻时，完全抵消了热电动势电压(VEMF)。
Note that the thermoelectric voltage (VEMF) is completely canceled out by this method of resistance calculation.
差分法的唯一优点是两个开关的偏移电压趋向于彼此抵消。
The only advantage of the differential method is that the offset voltages of the two switches tend to cancel each other.
电压前馈补偿可以抵消电网作用，使系统近似成为一个简单的无源跟随系统。
The feed-forward control of utility grid voltage counteracts the influence of utility grid. The system becomes a simple passive tracking system.
