摘要

This paper presents a current sensor-less hysteretic current mode switching power supply. Switching power supplies are controlled in the voltage mode or the current mode. The current mode converters are used in the power system which requires of high reliability because it has high stability of the feedback loop compared with the voltage mode converter. The current mode converter is necessary to detect the current. The efficiency of the main circuit is reduced by the current detection resistor. In the proposed method, the inductor current is predicted by solving the non-linear equations from the circuit analysis. The converter is operated in a hysteretic current mode using predicted inductor current. Therefore, it is unnecessary to detect the inductor current. It is able to eliminate the current detection resistor. It contributes to reduce the power loss of the main circuit. As a result, the proposed method can realize the operation in the hysteretic current mode and obtain excellent static characteristics without the current detection.
