Figure 1. Model of a RL series dipole The RLC series dipole is modelled by the scheme illustrated in figure 2. Figure 2. Model of a RLC series dipole 2.3. RC parallel dipole The variation of the voltage across the dipole is governed by equation (6). i(t) = C dv/dt +...
Power for any particular table column can be found using the appropriate Ohm’s power law equation. Power in Series and Parallel Circuits Power is a measure of the rate of work. Per the physics law of conservation of energy, the power dissipated in the circuit must equal the total power ap...
One way to increase power density is to increase the switching frequency of the overall solution. In a buck converter, each passive element in the circuit stores and releases energy during each switching cycle. The amount of energy buffered each cycle will be reduced at faster switching speeds....
For the open-circuit test, a nominal phase voltage is introduced in the primary coil, while the secondary coil is kept open (I = 0). Core losses are computed as below: As observed in the table, the simulated values are comparable to the values computed using mathematical formulas such as...
