Phase plane plots corresponding to load transient response using switching boundary control methods with second-order switching surface [155], deadbeat control [162], [163] and PWM control with large-signal tuning [168] using the parameter set in Table I In practice, the step size does not need to be known instantly, since the on-state trajectory continues until the intersection point with σ; there is a time interval between the disturbance and the intersection point that can be used for computation.…”

Many commercial controller implementations for dc-dc converters are based on pulse-width modulation (PWM) and small-signal analysis. Increasing switching frequencies, linked in part to wide bandgap devices, provide the opportunity to increase operating bandwidth and enhance performance. Fast processors and digital signal processing offer new computational techniques for power converter control. Conventional control techniques rarely make full use of operating capability. The objectives of this paper are to present an overview and link to literature on conventional modulation and control techniques for hard-switched dc-dc converters, identify performance limits associated with conventional small-signal-based design, discuss geometric control approaches, and compare strategies for control tuning. The discussion shows how current mode controls have alternative state feedback implementations, and describes unusual opportunities for large-signal control tuning. Considerations for minimum response time are described. Comparisons among tuning methods illustrate how geometric controls can achieve order of magnitude dynamic performance increases. The paper is intended as a baseline tutorial reference for future work on power converter control.

“…The inductor energy slews as quickly as possible to return to the reference voltage in the shortest time. This is a deadbeat control [162], meaning that there is complete transient recovery in finite time. Timing constraints can be added to enforce fixed frequency even through a transient [163].…”

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.

The Pseudo Continuous Current Mode (PCCM) operation of a boost converter can be treated as an intermediate between the Continuous Current Mode (CCM) and Discontinuous Current Mode (DCM) operation. The advantages in DCM operation and CCM operation can be effectively compromised to get this intermediate operation.In addition, the control flexibility and stability in DCM operation of a boost converter can be attributed to the PCCM operation as far as the control design is concerned. In this paper, three types of mode switched control designs based on the hybrid automaton model, namely, system theoretical design, circuit theoretical design and energy based design for a PCCM boost converter are analyzed and compared. Analysis, control design and simulation results are presented.
