Power optimizer solutions

Application-optimized, energy-efficient semiconductor products for single-panel and multi-panel optimizer designs

Overview

Power optimizers are DC-DC converters which provide maximum power point tracking (MPPT). MPPT is used to maximize power extraction under any environmental conditions, including changes in irradiation levels and temperature. MPPT can be implemented at the PV panel level or at the string level. MPPT at the PV panel level will provide larger energy yield. Additionally, power optimizers enable rapid shutdown (RSD) functionality and power monitoring.

About

Product offering for power optimizers

Power optimizers operate outdoors under harsh conditions; therefore, a compact form factor, high levels of efficiency, and a long lifetime are crucial success factors for these units. For example, in the case of failure, a replacement on the roof could be very expensive. Therefore, the market demands that power optimizers match the lifetime of a PV panel, which is typically 25 years. Infineon enables high quality and reliability standards through superior manufacturing processes, precise production screening, and automation.

Infineon offers a wide range of products with different packages and technologies, including OptiMOS™ MOSFET, EiceDRIVER™ 2EDL gate driver ICs, and XMC™, or PSoC™ high-performance MCUs, enabling manufacturers to design efficient solutions for single- and multi-panel optimizers. Furthermore, the portfolio contains our XENSIV™ high-precision Hall effect current sensors and EXCELON™ F-RAM when additional memory is required.

Switches™  for power optimizer solutions

Infineon's OptiMOS™ 5 technology offers a comprehensive portfolio for applications requiring MOSFETs from 60 V to 200 V, with a wide range of package options and RDS(on) granularity. Meanwhile, our cutting-edge OptiMOS™ 6 MOSFET technology enables ultra-high switching frequency domains.

Infineon's OptiMOS™ N-channel power MOSFETs are designed to increase efficiency, power density, and cost-effectiveness. Designed for high-performance applications and optimized for high switching frequencies, OptiMOS™ products offer the industry's best figure of merit.

Now complemented by our StrongIRFET™ and StrongIRFET™ 2 families of N-channel MOSFETs, this extended portfolio creates a truly compelling combination. These N-channel power MOSFETs add robust design and excellent price and performance to the best-in-class technology of OptiMOS™ MOSFETs. Both product families meet the highest quality and performance demands.

EiceDRIVER™  gate driver ICs for power optimizers

The EiceDRIVER™ 2EDL81 dual-channel junction-isolated gate-driver ICs are designed for medium-voltage power MOSFETs in half-bridge applications. 

Every switch needs a driver, and the right driver makes the difference. Infineon offers a comprehensive portfolio of EiceDRIVER™ gate driver ICs with a wide variety of configurations, voltage classes, isolation levels, protection features, and package options. EiceDRIVER™ gate driver ICs are complementary to Infineon's IGBT discretes and modules, silicon MOSFETs (CoolMOS™, OptiMOS™, and StrongIRFET™), silicon carbide MOSFETs (CoolSiC™), gallium nitride HEMTs (CoolGaN™), or as part of integrated power modules (CIPOS™ IPM and iMOTION™ smart IPM).

XENSIV™  current sensors for power optimizers

Infineon’s XENSIV™ family of high-precision coreless open-loop current sensors are less bulky and cost less compared to core-based current sensors. Based on Infineon’s precise and stable Hall effect current sensor technology, the current sensor analog output signal is highly linear over both temperature and lifetime. Due to the lack of an iron core or flux concentrator, the sensor signal shows neither hysteresis nor does it suffer from saturation. The differential current sensor measurement with two Hall cells ensures high accuracy even in a noisy environment like crosstalk from adjacent current lines or magnetic stray fields. System designers can program the sensitivity of the sensor as well as the threshold levels of the two dedicated overcurrent signals and therefore, adapt them to individual requirements without any external components. The contactless current sensor IC also provides a warning signal in case of an over- or undervoltage condition for the supply voltage.

32-bit XMC™  and PSoC™  6 industrial microcontrollers for power optimizers

A microcontroller unit (MCU) contains a CPU, memory, and input and output peripherals on a single integrated circuit (IC) chip, and functions as a small, standalone computer. This allows for a reduction in power consumption, more compact designs, and cost savings. Additionally, microcontrollers can provide functional safety and security for embedded systems.

It is critical that microcontrollers are equipped with advanced security features to avoid security compromises and prevent malware attacks. For this reason, the new generations of 32-bit MCUs provide robust protection for a range of embedded system applications. The Infineon microcontroller portfolio offers a comprehensive product range that includes state-of-the-art 32-bit microcontrollers that offer strong performance and future proven security solutions, along with traditional 8- and 16-bit microcontrollers.
