- 論文の詳細を見る
In this paper, a random-switching controller using chaos generators is employed in a DC-DC converter. By fluctuating the timing of the clock pulse for the converter, the controller can reduce the peaks of the power-spectrum of the output voltage. Different from the conventional controllers, the proposed controller exploits random noise generated by chaos generators. Therefore, the proposed controller can achieve effective reduction of the noise spectrum peak with small size of circuit. Concerning the controller designed by a 1.2 μm CMOS technology, SPICE simulations are performed to investigate the characteristics of the circuit. The SPICE simulations show that 1. the noise spectrum peak of the output voltage of the power converter is reduced more than 10 dB by employing the controller and 2. the circuit size for the proposed controller is smaller than that for the conventional controller. Furthermore, the validity of the circuit design is confirmed by experiments. The proposed controller will be applicable for most of switching power converters without design modification for the other parts.
