Isabellenhütte cooperated with different companies to develop 3 phase shunt modules for current sensing
of up to 100 A on the circuit board in frequency inverters. Apart from this, currents of up to 400 A can be measured with outstanding precision and long-term stability using the jointly developed power modules. In addition to that wire-bonded precision resistors can also be used in power modules depending on the customer requirements. The lecture is about the how and why of precision shunts in these applications.
