abstract = "In this study, a maximum power point tracking (MPPT) boost converter for module integrated converter (MIC) based solar power systems is proposed. Eight converters are series-connected to generate a 380 V DC-link voltage for a DCAC inverter system. The output current of the PV panel is controlled by each converter to operate at its maximum power point (MPP). The designed IC is composed of an analog frontend (AFE) and a current-mode boost converter controller. Digital MPPT is performed by a microcontroller (MCU) to ensure accurate operation. Fabricated in a 180 nm BCDMOS process, the IC has a die area of 12.5mm2. The single converter achieved power conversion efficiency of up to 97.1\%. The stable operation of a three-converter stack was also verified.",
