This paper proposes an interesting control technique which cancels the transfer function of the converter by using pole-zero-cancellation method. The system stabilization design is easy to be realized by applying this technique. The impaired system stability caused by parameter variation is investigated, especially the influence of the output capacitance variation. Moreover, a parameter tracking method...
The trend in Plasma Display Panel (PDP) TV is towards the thinner thickness, lighter weight, and fan-less system. For achieve this goal, it is desired advanced power conversion technique to implement a low-profile power supply for PDP. As PDP power module, LLC resonant converter is widely used because it can achieve both high efficiency and reliability. To achieve a low-profile circuit configuration,...
Recently, the performance of the DSP and FPGA is developed remarkably. So, fully digital control is enabled in switch mode power supplies. However, in many cases, the control system is built by very complicatedly and very difficult theories such as the adaptive control, predictive control, and so on. Furthermore, in most popular PID control, its design method of the parameters is not clear, so derivation...
POL with peak current mode control has first-order response depending on the controller design, and the overshoot and undershoot donpsilat appear in transient response. This feature is the chief advantage of peak current mode control. However, there is no example of the design that employed this feature efficiently. This paper investigates the design consideration for first-order response of peak...
