Experiment FT2: Measurement of Inductance and Mutual Inductance
... If the secondary circuit is closed, for example, by connecting a resistor to the terminals, a current I2 will start to flow. By this electromagnetic induction, the electrical energy is transferred from the primary winding to the secondary winding by means of magnetic field coupling. Assuming that th ...

3D Finite Element Analysis for Arcing Chamber Optimization
... The paper presents the calculation of the magnetic field in the arcing chamber of the current-limiting circuit breaker of the direct current 1250 A, 750 V. Current-limiting circuit breakers play an important role in electrical low-voltage circuits. Due to the high short-circuit currents it is necess ...

Development of Micro-Vacuum Arc Thruster with Extended Lifetime
... A PPU similar to that used previously in Ref. 2, was employed in the current work. The PPU operates in two steps (see Figure 2). On the first step, when the switch (IGBT transistor was used) is open, the inductor used in the circuit is charged by the DC power supply (20-30 V). On the second step, en ...
