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.

“…The variation of the applied magnetic field strength leads the magnetic material to operate in the different regions of the magnetization curve, from a linear region, where the differential permeability shows a near-constant profile, to a roll-off region, in which the permeability rapidly decreases, finally to a saturation region, where the minimum value of the differential permeability is obtained, and the material is fully saturated [36].

In this work, a control strategy for a Class-E inverter for Capacitive Wireless Power Transfer (CWPT) application is proposed. The presented approach allows to stabilize the output power regulating the components values of the resonant tank. A matrix of capacitors is used to adjust the values of capacitances and the magnetic design procedure for the variable inductor is proposed. The obtained performances are evaluated through Plecs simulations and compared with the case without a control strategy.

“…This strategy is exploited in several other works 15,16,57,78 and is also generalized for the case of discontinuous conduction mode (DCM) operation. 79 A similar iterative method is adopted in other papers, [80][81][82] where the current waveform is computed through successive approximations.…”

Summary Switch‐mode power supplies (SMPSs) are widely exploited to interface electrical energy sources to motors and other electrical loads. Inductors are usually the biggest and heaviest components in SMPSs, limiting their overall power density. Therefore, there is an increasing interest in designing SMPSs with partially saturating inductors, because this significantly reduces their weight and size, thus increasing power density. This paper provides a review of nonlinear behavioral models (based on easy‐to‐measure quantities) of the inductance, power loss, and temperature rise of inductors working, at least partially, in magnetic saturation. This survey discusses the pros, cons, and ranges of validity of these models, with a glimpse at their application to SMPS simulation, design, monitoring, and control.
