Many practical photovoltaic power generation systems with higher output voltage levels rely on photovoltaic DC boost converters with high frequency and high efficiency, which performance directly affect the conversion efficiency of photovoltaic power generation systems. This paper investigates a high-frequency and high-efficiency photovoltaic DC boost converter, which adopts the Boost full-bridge isolation circuit topology with active clamps. The conductance increment method is used as the maximum power point tracking algorithm. The small signal models of its power circuit and control circuit are established to obtain the system model and analyze its stability. The simulation results indicate that the ripple coefficient of output current is less than 3%, and the ripple coefficient of output voltage is less than 5%, which meets the stability requirements.

Interface Circuit

<span>A battery-less energy harvesting interface circuit to extract electrical energy from vibration has been proposed in this paper for low power applications. The voltage doubler integrated with DC – DC boost converter circuits were designed and simulated using MultiSIM software. The circuit was then fabricated onto a printed circuit board (PCB), using standard fabrication process. The Cockcroft Walton doubler was chosen to be implemented in this study by utilizing diode-capacitor topologies with additional RC low pass filter. The DC – DC boost converter has been designed using a CMOS step -up DC – DC switching regulators, which are suitable for low input voltage system. The achievement of this interface circuit was able to boost up the maximum voltage of 5 V for input voltage of 800 mV.</span>
