It is observed that as the size of the compensation capacitor is increased, the low-frequency pole location ω1 decreases in frequency, and the high-frequency pole ω2 increases in frequency. The poles appear to “split” in frequency.
Objective of compensation is to achieve stable operation when negative feedback is applied around the op amp. Miller - Use of a capacitor feeding back around a high-gain, inverting stage. Miller capacitor only Miller capacitor with an unity-gain buffer to block the forward path through the compensation capacitor. Can eliminate the RHP zero.
Compensation capacitors are divided into two type families (A and B) in accordance with IEC 61048 A2. • Type A capacitors are defined as: "Self-healing parallel capacitors; without an (overpressure) break-action mechanism in the event of failure". They are referred to as unsecured capacitors.
It should be noted here that the value of the capacitance used in the compensator design must be the small signal value. Ceramic capacitors lose some portion of their capacitance as their biasing voltage increases. The MLCC capacitors which are used in this example have 22μF nominal capacitance.
In addition, a better understanding of the internals of the op amp is achieved. The minor-loop feedback path created by the compensation capacitor (or the compensation network) allows the frequency response of the op-amp transfer function to be easily shaped.
Compensation of the output-buffer dead-zone region is provided by Q18 and Q19. Output-current limiting and short-circuit protection is imple-mented by Q15 and Q21–Q25. And of course, the frequency compensation is accomplished by the 30 pF capacitor around Q16 and Q17, as discussed in Section II. Fig. 45.
Compensation Capacitors
Compensation capacitors are used to counteract reactive current (increased power factor) and are basically either connected in parallel or in series. Compensation capa-citors are not required when using electronic ballasts, whose power factor is generally in the region of 0.95.
