WebAug 22, 2024 · Predictive system maintenance and protection require fast acting system responses. One of the pivotal functions that allow the above, is monitoring the current consumption and voltage drops across the system. Amongst all the current sensing methods, by far, the most popular method is monitoring the current across a shunt using … WebIn-line current sensing. Inline current sensing technique is the simplest one to use and the most precise one. The shunt resistors are placed in-line with motor phases and the current measured on these shunt resistors will be motor phase current regardless of the state of the PWM duty cycle.
WebThe voltage over the shunt could be measured by differential amplifiers, for example, current shunt amplifiers, operational amplifiers or difference amplifiers. It is typically implemented for load currents <100A. 2. Indirect current sensing: Indirect current sensing is dependent upon Ampere’s and Faraday’s laws.
