The answer maximizes power effectivity with an built-in photo voltaic charger and LED driver, providing MPPT know-how, versatile battery assist, and security.
Cypress’s MPPT Photo voltaic Charger and LED driver reference design are based mostly on the PowerPSoC answer. It fees solar-powered lead-acid batteries utilizing a Most Energy Level Monitoring (MPPT) algorithm, which tracks the height energy from the photo voltaic panel to maximise power harvesting and enhance battery charging effectivity. The identical PowerPSoC gadget additionally drives the LEDs. This answer is appropriate for avenue and photo voltaic lighting functions, offering environment friendly power administration and dependable efficiency for out of doors and off-grid lighting methods.
In contrast to different options connecting the battery on to the photovoltaic modules, the MPPT algorithm controls the charging present. This permits the system to function at most energy even at night time, boosting the ampere-hours delivered to the battery and enhancing the fixture’s effectivity. The reference design helps numerous lead-acid battery varieties, together with flooded, absorbed glass mats, sealed, and gel batteries.
PowerPSoC makes use of its inner options for LED driving, reminiscent of 6 MHz present amplifiers, 2 MHz hysteretic controllers, 16-bit dimming, and exterior gate drivers to implement a floating load buck and enhance drive. This built-in answer gives a number of load management choices, together with automated dusk-to-dawn operation, battery charging, and cargo enabling. PowerPSoC additionally consists of security options for the charging circuit, reminiscent of safety in opposition to over-voltage, no battery connection, battery under-voltage, and low panel voltage.Â
The powerSOC consists of PSOC 4, which simplifies complicated embedded system design, serving to you convey your product to market sooner. It integrates and optimizes features like analogue sensor integration, capacitive contact, and wi-fi connectivity to work seamlessly.
The MPPT algorithm optimizes photo voltaic power harvest by modulating the battery charging present to extract the very best energy from the photo voltaic panel. It really works effectively with numerous battery varieties, together with flooded, absorbed glass mats (AGM), sealed, and gel batteries, which will be chosen by way of jumper configuration. This considerably improves ampere-hours delivered to the battery, supporting a 12V lead-acid battery with a most charging present of 9.5A.
The built-in high-power peripherals present a cheap answer. The system features a enhance driver rated at 40V and 1A and a buck driver rated at 8V and 1A, providing a number of load management choices. The MPPT and LED drive performance are mixed on a single chip, making certain environment friendly power administration.
Security options are enhanced with clever flexibility. The system consists of protections for battery overvoltage, no battery connection, battery undervoltage, and low panel voltage. It additionally supplies a number of safety choices for the photo voltaic panel, together with reverse polarity, overvoltage, undervoltage, open circuit, and quick circuit protections.
