In this paper, a novel digital control algorithm is proposed to achieve an excellent dynamic performance for two-transistor forward converter. By using the charge balance control(CBC), the optimal transient time and the suitable duty cycle series can be predicted, then better transient performance can be obtained. A comparison of dynamic performances between CBC and conventional voltage mode control...
In this paper, a new digital control algorithm is presented to improve the dynamic performance of the dual-transistors forward converter (DTFC) during a transient event. The algorithm uses a linear control scheme under the stable-state condition and the charge balance control scheme under the transient condition. Based on the principle of capacitor charge balance, the proposed algorithm predicts the...
Recently, optimal control on Buck converter for powering the latest computer central processor units (CPUs) has attracted more and more attention. In this paper, a novel digital control algorithm is presented to achieve the time-optimal response for dc-dc Buck converters without relying on any knowledge of converter design parameters such as output inductance, capacitance and even ESR value. This...
The paper presents a new version of the modified nodal method in transient behavior (the semi-state equations) for the analysis of the circuits driven by signals with widely separated time scales. The key idea is to use multiple time variables, which enable signals with widely separated rates of variation to be represented efficiently. The semi-state equation formulation in a partially symbolic form...
