Application of Buck PWM converters for Class-S amplifiers is well known. For high frequency Class-S applications above 1 Mhz, application of the SEPIC instead of the Buck converter can result in enhanced amplifier stability and lower cost. To realize these advantages, a ramp function is presented which improves the linearity of the SEPIC’s open loop voltage gain transfer function.
