Mixed Analog Digital (MAD) Converters for High Power Density DC-DC Conversions

Conventional switched-mode power supplies have intrinsic instantaneous power pulsation at the switching frequency thus require bulky filters. To improve the power density, this paper proposes a concept named the mixed analog-digital (MAD) which can be applied as dc-dc converters. By inserting an analog voltage component between the load and source, the output voltage naturally has much smaller flu...
