The chip integrates deterministic high-speed control hardware, four 100 Msps analog-to-digital converters (ADCs), custom power line communication and low voltage differential signaling (LVDS) controllers, hardware-enforced isolation, cryptography, secure boot, and functional safety features. By moving these capabilities into silicon, Kestrel is designed to reduce system complexity while preserving the speed, cost structure, and field reliability required for grid-connected power electronics.<\/p>\n<p>&#8220;Kestrel is an important milestone because it turns Enphase\u2019s custom silicon into a reusable platform for multiple product families,&#8221; said Raghu Belur, co-founder and chief product officer of Enphase Energy. &#8220;The white paper shows how one ASIC can help us carry proven power conversion intelligence across microinverters, batteries, bidirectional EV charging, and solid-state transformer modules while supporting the reliability, security, and cost structure required for products deployed at grid scale.&#8221;<\/p>\n<p>The paper highlights Kestrel&#8217;s role in enabling high-frequency operation with gallium nitride (GaN) bi-directional switch technology. Enphase&#8217;s single-stage, dual-active-bridge, series-resonant cycloconverter topology requires cycle-by-cycle knowledge of resonant tank current and voltage, with gate transitions timed at hundreds of kilohertz and nanosecond-scale precision. Kestrel moves this control loop out of firmware and into deterministic custom hardware connected to the ADC outputs and gate-drive command infrastructure, supporting closed-loop control bandwidth exceeding 100 kHz while maintaining soft switching and low switching losses.<\/p>\n<p>For the IQ SST power module, Kestrel supports a tandem control architecture across a medium-voltage isolation boundary. Two Kestrel ASICs \u2013 a controller on the low-voltage side and a device on the medium-voltage side \u2013 exchange time-critical measurements, FET control information, shutdown requests, and remote chip access over fiber-optic links driven by Kestrel&#8217;s custom LVDS controller. This approach eliminates an external processor or flash device on the medium-voltage board.<\/p>\n<p>The paper connects this architecture to a key AI data center challenge: GPU rack loads that can swing from low to high utilization multiple times per second. Kestrel&#8217;s hardware power controller and tandem SST architecture are designed to support sub-millisecond transient response, native three-phase operation, and high-frequency soft-switching conversion between medium-voltage AC distribution and low-voltage DC buses. By responding in less than 1 ms, the IQ SST architecture is intended to eliminate local super-capacitor or battery energy buffering near compute racks.<\/p>\n<p>&#8220;Kestrel was designed because the control problem cannot be solved well enough with a commodity microcontroller,&#8221; said Hans van Antwerpen, chief technology officer of Enphase Energy. &#8220;The ASIC integrates the high-speed ADCs, deterministic power-control hardware, protection units, security engines, and tandem fiber-link functions needed to control GaN-based resonant converters safely, securely, and at very high frequency. That is what allows the same silicon foundation to support microinverters and also scale into solid-state transformer applications for dynamic data center loads.&#8221;<\/p>\n<p>The white paper also covers Kestrel&#8217;s security and functional safety architecture, including processor islands, cryptography accelerators, identity-based access control, ROM-rooted secure boot, hardware AES and SHA acceleration, true random number generation, certificate-based public key infrastructure support, lifecycle management, single-bit error correction, double-bit error detection protection, DMA memory scrubbing, watchdog timers, and centralized fault handling.<\/p>\n<p>To read the white paper, please visit the Enphase <a href=\"https:\/\/www.globenewswire.com\/Tracker?data=SgYFXzuIvlWQ55smaZ0cwICNau7l-cy-1UM2Qzq1XNv48JRR0Ac4gwY3eQvwvEqSn4s52I-nILH5Y-YoRn4i4hoY8X2sV9MgEhkXJ5OObXXoSrczPhwCog1qMX8uwGHTTJRdkStixjoFcLmiu6MTpA==\" rel=\"nofollow\" target=\"_blank\">website<\/a>.<\/p>\n<p>\n        <strong>About Enphase Energy, Inc.<\/strong>\n      <\/p>\n<p>Enphase Energy, a global energy technology company based in Fremont, CA, is the world&#8217;s leading supplier of microinverter-based solar and battery systems, EV chargers, home energy management systems, and virtual power plant (VPP) solutions.
