This paper presents the dynamic characteristics of the proposed digital control current mode dc-dc converter. In the proposed novel digital control circuit, the peak current-injected control is realized using the combination of the simple dual A-D signal converter and the programmed delay circuit. In 100 kHz digitally controlled dc-dc converter, it is seen in simulation that the proposed method has...
Recently, progress of PLD (programmable logic device) like FPGA or CPLD makes it realize the digital control system of power electronics without microprocessor (CPU or DSP). Complex control algorithm can be implemented into FPGA and the calculation time can be dramatically reduced based on parallel processing hardware circuit. But commercial based controller board for power electronics is mainly designed...
This paper presents a new digital control circuit which is able to detect the peak switch current of the high frequency switching dc-dc converter. In this proposed digital control circuit, the peak current-injected control is realized using the combination of the simple dual pulse width modulation analog-to-digital signal converter and the programmed delay circuit. In 100 kHz digitally controlled...
