The linear power amplifier (LPA) suffers from low power supply utilization in the DC power supply mode, leading to reduced output efficiency. This paper constructs an efficient power supply mode based on closed‐loop dynamic power supply system (CLDPSs). The CLDPSs can generate a pair of bipolar dynamic power supplies based on a predetermined signal to provide power to LPA, which can maintain a small voltage drop between the power supply and the output of LPA, thereby improving the power supply utilization of LPA. In addition, the study also focuses on the conflicting relationship between the output ripple and the dynamic performance of the CLDPSs, for which a new parametric design of the LC filter circuit is proposed, aiming to achieve a balance between these two aspects. Finally, a voice coil motor driving platform is constructed for experimental testing. The results demonstrate that the output ripple and dynamic performance of the CLDPSs can be balanced. In comparison to the DC power supply mode, the CLDPSs power supply mode can enhance the efficiency of LPA by 2 times while the driving accuracy of voice coil motor is basically unchanged.

To meet the supply voltage of some Marine equipment related performance test, the power supply is designed with wide threshold adjustable value. In DC-DC transformation, Buck circuit is a common step-down topology. The adjustable voltage power supply system is composed of Buck synchronous rectification circuit, drive circuit, power supply circuit, voltage sampling circuit, current sampling circuit, control circuit, and so on. STM32F407 of STMicroelectronics is used as the main control chip to provide PWM for the driving switch device MOS. The voltage feedback circuit is used to calibrate the output voltage to ensure the accuracy of the output voltage.
