4 Frequently Asked Questions about "Phase compensation of base station power supply"

Is a type 2 compensation network suitable for buck converter power stage?

Consequently, the buck converter power stage including the current loop behaves as a single-pole system at lower frequencies below the current loop bandwidth. Therefore, a simple Type 2 compensation network is adequate to optimize supply loop stabilities and transient performances.

What is power supply loop compensation design?

Power supply loop compensation design is usually viewed as a difficult task, especially for inexperienced supply designers. Practical compensation design typically involves numerous iterations on the value adjustment of the compensation components.

How does phase compensation work?

In this system, the phase compensation is configured by connecting resistor RITH and capacitor CITH in series with the output of the error amplifier . Rea represents the output resistance of the error amplifier, Vref is the reference voltage, and VFB is the feedback reference voltage (Figure 1). Figure 1. Phase compensation circuit diagram 2.

What is a good phase margin for a power supply?

A 60° phase margin is a good result. A faster response to current load changes is achieved when the bandwidth (BW) of the power supply design is wider. The BW of the power supply is where the 0 dB gain crosses the frequency axis. Also known as the crossover frequency, Fc, the phase at this point is observed to be higher than 45°.
