Abstract(in English) | This paper proposes new EMI reduction method with spread spectrum using psuedo analog noise which is produced from M-sequence circuit with LPF and PLL circuit. The PLL circuit with analog noise makes the phase modulated clock pulses. Our new M-sequence circuit makes the period of 112 patarn clock's length with only 3-bit counter. Adapting this analog spread spectrum method to DC-DC switching buck converter, the spectrum level of PWM signal is reduced about 1/10 from normal PWM signal level. |
