| Abstract |
In this paper, we propose a novel software defined power supply using the general purpose DSP (Digital Signal Processor) and its control algorithm based on power supply on chip. The proposed power supply can regulate the output voltage only loading a program into the DSP without adjusting the parameters and changing the external parts. Also, it can change the output voltage according to the state of the load by executive instruction from the load. The simulation results show that the transient response depends on the inductance, the capacitance and the internal resistance, and expects sub-µ s. at switching frequency of 30 MHz. |
