Switching power converters connected to dc loads need high stability because the dc bus voltage is fluctuated in the hybrid energy system. The aim of this paper is to present stability characteristics of a digital peak current control dc-dc converter regarding input voltage fluctuation. The proposed method shows higher stability than the digital voltage mode control method even though the input voltage...
The aim of this paper is to present static and dynamic analyses of digital peak current mode dc-dc converter. The current detection circuit of the proposed method consists of RC integrator and comparator as the AD converter. The proposed method can detect the peak current in real time. Analyses and the transient response of proposed method are discussed in this paper. As a result, the convergence...
The purpose of this paper is to present the transient response in the proposed digitally controlled dc-dc converter under the various changes. The digital PID control circuit has a delay time mainly due to the calculation and sampling. This delay time heavily affects the transient responses. In the proposed method, a twist is added to the PID control in order to achieve fast response. In addition,...
