Modern computation and communication integrated circuit are continually powered from a lower voltage with stringent static and dynamic limitations. The power supplies with hysteretic modulators exhibit superior dynamic performance and help reduce the number of output capacitors without sacrificing transient response. The synthetic ripple modulator (SRM) allows proper hysteretic operation even with...
It is more difficult for VRMs to supply power to future microprocessors, which need lower supply voltage, large current and large current slew rate. Most of today's VRMs are with inductor-capacitor type output filters. The inductor in the output filter limits the current transient speed. Hence, the secondary-side controlled series resonant converter with capacitor type filter is introduced in this...
This paper presents an analysis of three-phase self-excited induction generator (SEIG) with static compensator (STATCOM) as a voltage regulator. Current controlled voltage source inverter is used as STATCOM, which provides fast dynamic response to maintain constant voltage at SEIG terminals during severe load perturbation and acts as a source or sink of reactive power. The dynamic model of SEIG is...
