As we know, the pulsed power supply generally includes inductors, capacitors [3], pulsed alternators and homopolar generators [4]. The pulsed alternators integrate inertial energy storage, pulse shaping and power conditioning into one unit, and it has drawn a great deal of attentions in recent decades due to its high energy density, high repetition
Demagnetization Energy Equation 1 defines the energy stored in an inductive load, and Equation 2 defines the energy dissipated by the high-side switch: (Eq. The traditional way to specify the sensitivity of an analog IC to power supply variations is the power supply rejection ratio (PSRR). For an amplifier, PSRR is the ratio of the change
