Nonlinear Control Method of Multi-phase Interleaved Buck/Boost Converter Applied to Pulse Switching Power Amplifier

This paper proposes an improved passive control method applied to the multi-phase interleaved buck/boost converter with a pulse-type switching power amplifier to compensate for the power fluctuations in pulsed loads and suppress the double-frequency ripple. The stability of the system is achieved, while the output steady-state accuracy and dynamic performance are improved.
