This paper proposed an improved dual-edge modulation (IDM) for digital average voltage (DAV) controlled switching converters. The DAV control can regulate the output voltage of switching converter without a PI compensator. Different from the conventional symmetrical dual-edge modulation (SDM) method, the IDM has double sampling points in one switching cycle, which ameliorates the transient performance...
In order to improve the output-regulation accuracy of the switching converter with conventional constant off-time (CCFT) modulation, dual-edge constant off-time (DCFT) modulation for switching converter is proposed in this paper. The principle of switching converter with DCFT modulation, including leading-triangle constant off-time (LT-CFT) modulation and trailing-triangle constant off-time (TT-CFT)...
Constant on-time (COT) digital peak voltage (DPV) control of switching dc-dc converter is proposed in this paper. The COT-DPV control technique is investigated and compared with pulse width-modulated DPV (PWM-DPV) control technique by taking COT-DPV and PWM-DPV controlled buck converter in continuous conduction mode (CCM) as an example. The steady-state and transient performances of COT-DPV and PWM-DPV...

This paper deals with specific problems encountered when full digital control is applied for the boost-type power factor correction (PFC) converter. The robust performance, voltage regulation and sample frequency of the proposed controller are highlighted. Compared with traditional design, a novel input voltage feed-forward control algorithm is proposed to reduce the closed-loop time constant and...

The proposed control method applied for SIDO converters operating in continuous conduction mode (CCM) realizes independent control of each output of the SIDO converter to reduce the cross-regulation problem. Simulation results...
Multi pulses regulation (MPR) control technique, a novel control technique for the control of switching DC-DC converter is proposed. Unlike traditional Pulse Regulation (PR) control technique which realizes the control of switching DC-DC converters by the corresponding combination of two different pulses, MPR control technique extends these two different pulses to multi pulses, and thus overcome some...
