This paper presents an adaptive slope compensation method for peak current mode control of digital controlled DC-DC converters, which controls the quality factor of the complex conjugated poles at half the switching frequency. Using quality factor control enables optimization of the dynamic performance and stability of current mode control. The presented method adapt to DC-DC converter operating conditions...
In this paper, a high performance fully digital peak current mode controller for DC-DC converters which supports the full duty cycle range from 0–100% is presented. Support for low duty cycle is very important during short circuit or converter overload and support for high duty cycle is important for faster response during a transient and for providing a larger output voltage range. The digital current...
This paper presents an experimental flexible Field Programmable Gate Array (FPGA) based platform for testing and verifying digital controlled dc-dc converters. The platform supports different types of control strategies, dc-dc converter topologies and switching frequencies. The controller platform has a synchronized load change mechanism and build-in acquisition memory, which makes it possible to,...
An adaptive control technique for a digital current mode control of dc-dc converters is proposed in this paper. The adaptive digital controller is designed to maintain the optimum gain-phase of the outer control loop regardless of the changes in the load value. In the control algorithm, the load resistance is calculated using the average current and output voltage values inside the digital processor...
This paper presents a Digital Predictive Peak Current Mode controller which uses inductor inductance estimation to estimate the inductor current slopes and to predict the inductor current in both discontinuous and continuous conduction mode. The estimated current slopes are used for controlling the current loop. The proposed controller is implemented in a Field Programmable Gate Array (FPGA) to control...
