“…Unlike other research methods, the proposed control strategy does not need many try and-errors or many parameters to be tuned. Since there are three parameters in the PID controller, there are many possible combinations [\] [5][13]- [15]. In order to reduce variables for design convenience, only the parameter KJ is adjusted during the fast transient region, and at the same time, Kn is set to zero.…”

In this study, a PID controller with the proposed control strategy is presented, which is used to improve the load transient response. During the load transient period, the parameters of the proposed controller are on-line adjusted and make the controller design easy. As compared with the traditional PID control, the proposed control strategy does not need additional hardware circuits. In addition, the corresponding calculation flow chart is varied as minimum as possible, such that the parameters of the PID controller is of easiness and generality.

“…Time-domain modeling of a DC-DC converter power stage in VERILOG and VHDL, allow the digital designers to simulate and debug different algorithms in their controller design in the form of a complete closed-loop feedback. Examples include but not limited to: non-linear control technique [23][24][25][26][27][28][29][30], dead-time optimization [31,32], current sharing [17], phase adding/shedding [19], voltage/current measurements, under/over voltage and current protection [33], etc.…”

This paper introduces a simple and fast method of time domain simulation for switching converters. Different discrete time modeling like Forward, Backward and Trapezoid rules are used. It is shown that the discrete time equations can be derived using dual or oversampling techniques. The methods can be implemented using any computer language programs or mathematical tools. These methods are particularly useful for IC controller designers, application engineers and the end-users. Simulation results are shown for a synchronous and a dual phase buck converter. It is shown that the proposed method can successfully model a switching converter in the time domain.

“…Several adaptive control methods are discussed in the literature that improves the dynamic performance of power converters [17][18][19]. Adaptive control methods that vary the parameters of the compensator are proposed in [17][18] to improve the transient performance of power converter. Switching adaptively between two compensators is presented in [19] which results in an improvement of transient response.…”

This paper presents a control scheme that varies the switching frequency of switching power converter in order to improve its dynamic transient performance. The proposed method adaptively varies the switching frequency of the converter during transients as a function of the error signal. The control law and its implementation are presented. Experimental results from a proof of concept experimental prototype are presented that illustrates the dynamic performance improvement with the proposed control scheme.
