Modulation scheme for filterless switching amplifiers with reduced EMI |
摘要 |
A ternary modulation scheme for filterless switching amplifiers with reduced EMI reduces the common mode component of the signal by allowing only one state with zero differential voltage across the load to exist. The ternary modulation scheme is more efficient than the quaternary modulation scheme when applied to class-D filterless switching amplifiers since the gates of the power MOSFETs are being charged and discharged at only a small duty cycle instead of 50% duty cycle.
