High efficiency solar battery charger with embedded MPPT The SPV1040 is a high efficiency, low power and low voltage monolithic step-up converter that operates over a 0.3 V to 5.5 V input voltage range which allows providing power supply to products using even down to one photovoltaic cell or fuel cells where the capability of handling low input voltages is of utmost importance. Despite the variation of several conditions over the day like irradiation, dirt, temperature, etc. the SPV1040 allows to achieve the maximum efficiency in terms of power harvested from the cells and transferred to the output thanks to the embedded MPPT algorithm. It employs an input voltage regulation loop, which fixes the charging battery voltage, set with a resistor divider and a maximum output current set with a current sense resistor according to charging current constraints. The SPV1040 guarantees safety of application devices and of the converter itself stopping the PWM switching in case either of reached maximum input current peak threshold set up to 1.8 A or maximum temperature limit set up to 155 ℃ . As additional feature the IC build-in an input source reverse polarity protection which prevents damaging in case of reverse connection of solar panel at the input.

Startup is guaranteed at 0.3 V and the device operates down to 0.45 V when coming out from MPPT mode. It is a 100 kHz fixed frequency PWM step-up or boost converter able to maximize the energy generated by few solar cells polycrystalline or amorphous. The duty cycle is controlled by an embedded unit running an MPPT algorithm with the goal of maximizing the power generated from the panel by continuously tracking its output voltage and current. The SPV1040 guarantees the safety of overall application and of converter itself by stopping the PWM switching in the case of an overcurrent or overtemperature condition. The IC integrates a 120 m Ω N-channel MOSFET power switch and a 140 m Ω P-channel MOSFET synchronous rectifier. 图 5.采用 SPV1040 的典型应用电路图 6.太阳能电池充电器 STEVAL-ISV006V2 外形图图 7.
