Microsemi targets solar conversion
With the availability of its solar technology portfolio, Microsemi’s products for renewable energy applications now include SmartFusion and IGLOO FPGAs analogue, mixed signal devices and pulse width modulation (PWM) modules, targeting the entire range of photovoltaic (PV) applications, including power harvesting, power management, power switching and power monitoring.

The LX2400 IDEAL Solar Bypass Device with Microsemi’s patented CoolRUN technology provides a bypass path in PV module applications. With the industry’s lowest forward voltage drop, resulting in negligible heat generation and temperature rise during operation, the LX2400 is best in class for reliability and robustness, in applications that require currents on the order of 10 amps or more through a module’s junction box.

At only 0.74 mm high, Microsemi’s new Schottky Barrier PV bypass diodes are claimed to be the thinnest in the world, allowing customers to integrate them under the glass, eliminating the need for junction boxes. Alternatively, the ultra thin dimensions can be used to shrink the size of the junction box. Designed specifically for solar panels, the SFDS series of 10 amp diodes are packaged with unique flexible copper leads that offer satellite-proven reliability.

Microsemi also offers a wide range of Schottky bypass diodes in axial, surface mount and thru hole devices. The standard current range is 10 A to 18 A with voltages ranging from 20 V to 45 V, but the possibility to design and build custom devices up to 60 A and up to 200 V also exists.

Microsemi’s flash-based architecture utilized in SmartFusion mixed signal FPGAs and IGLOO low power FPGAs is ideal for helping inverter designers maximize efficiency and integration of board-level functionality into a smaller footprint. Functions and algorithms such as increased number of PWM state machines, Maximum Power Point Tracking (MPPT) and Power Factor Correction (PFC) can be partitioned in the embedded 32-bit ARM CortexTM-M3 or within logic gates to suit the individual design requirements.

The new 600 V CoolMOS C6 devices feature fifth-generation high voltage superjunction technology for extremely low conduction and switching losses, enabling the design of switching systems that offer new levels of efficiency and power density.
