Perfect for small to medium-power functions, it options GaN FET expertise, delivering as much as 98.8% effectivity, a compact type issue, and sturdy protections.
A Most Energy Level Monitoring (MPPT) photo voltaic cost controller is a essential element for environment friendly photo voltaic vitality administration. This reference design caters to small and medium-power photo voltaic charger functions, making it very best for photo voltaic cost controllers and energy optimizers utilized in residential, business, or transportable photo voltaic methods. Focused at designers and engineers, it gives a flexible resolution able to working with 15V to 60V photo voltaic panel modules and supporting 12V or 24V batteries. With a compact type issue and excessive effectivity, this design is appropriate for methods requiring as much as 16A output present.
The reference design TIDA-010042 by Texas Devices (TI) makes use of a buck converter to step down the photo voltaic panel voltage to the battery voltage. It encompasses a half-bridge TI gallium nitride (GaN) energy stage with built-in drivers managed by an MSPM0G1506 microcontroller unit (MCU). The MCU employs the perturb-and-observe algorithm to dynamically determine the utmost energy level, guaranteeing optimum vitality extraction from the photo voltaic panels. The design achieves spectacular effectivity ranges of 98.5% for 12V methods and 98.8% for 24V methods, due to the GaN FETs with low RDS(on), decreased switching losses, and 0 reverse restoration cost. The excessive switching frequency of as much as 250 kHz permits using compact passive elements, decreasing general design dimension.
This MPPT photo voltaic cost controller incorporates a number of protections to reinforce reliability, together with reverse battery polarity, overcharge, over-discharge, and system overtemperature safety. Moreover, the controller consists of programmable alarms and indications, together with surge and electrostatic discharge (ESD) safety, making it sturdy for numerous environmental circumstances. Its small board dimension (83mm × 82mm × 26mm) additional simplifies integration into compact methods.
Key options of this design embody a large enter voltage vary (15V to 60V), versatile compatibility with 12V and 24V batteries, and help for top output currents as much as 16A. Purposes vary from photo voltaic cost controllers for residential or off-grid methods to solar energy optimizers that maximize vitality harvesting in small and medium-scale setups.
TI has completely examined this reference design, guaranteeing its reliability and efficiency.
