The wide 4.75- to 9.5-V supply-voltage range allows for convenient connection to an existing power rail. MasterGaN4 is well-suited for use in symmetrical half-bridge topologies as well as soft-switching topologies like active clamp flyback and active clamp forward. Leveraging the higher operating frequencies enabled by the superior switching performance of GaN transistors, as well as their increased efficiency that reduces thermal dissipation, designers can choose small magnetic components and heatsinks to build more compact and lightweight power supplies, chargers, and adapters. With inputs tolerant of voltages from 3.3 to 15 V, MasterGaN4 can be controlled by connecting the packages directly to Hall-effect sensors or a CMOS device such as a microcontroller, DSP, or FPGA. The MasterGaN4 facilitates design using wide-bandgap GaN power semiconductors by taking away the complex gate-control and circuit-layout challenges. The configuration helps simplify the design of high-efficiency power-conversion applications up to 200 W.

STMicroelectronics’ MasterGaN4 power packages integrate two symmetrical 650-V gallium-nitride (GaN) power transistors with 225-mΩ R DS(on), alongside optimized gate drivers and circuit protection. Co-Packaged 650-V GaN Transistors Optimized for Power-Conversion Apps Up to 200 W The Cleanwave200 evaluation system, reference design, and design files can be ordered from Pre-Switch. To assist design engineers in evaluating the new technology, Pre-Switch has published data plots of the evaluation inverter's system efficiency at multiple switching speeds between 50 and 100 kHz, with multiple input voltages, power and current outputs. Click here to see the animated demonstration and get a more detailed explanation of how the Pre-Switch controller works. It begins with unknown starting conditions and ultimately optimizes the timing and other adjustments necessary to ensure that a pulse-width-modulated (PWM) input generates a current ramp to simulate the first part of a sine-wave output. This is a snapshot of a live demonstration of the CleanWave200 evaluation system, illustrating the Pre-Switch controller's AI actively learning during initial startup. The CEO also says that when used in EVs, the AI-enabled inverter's high efficiency and reduced motor losses at the lower torque outputs typically used by motorists can add up to 12% to the vehicle's range. Key applications include electric vehicles, solar inverters, wind turbines, UPS, storage, and motor drives. Renouard notes that the cleaner output and higher switching speeds made possible by the controller's self-learning algorithms yield the high conversion efficiencies, which, in turn, enable designers to create more compact applications that require fewer, smaller passive components and heatsinks. "This enables many applications to produce an almost pure sine wave output,” he says, “while running at to four to ten times the switching frequency of a conventional circuit.” Variations in system temperature, device degradation, changing input voltages, and abrupt current swings are all accounted for and optimized within the Pre-Switch AI algorithm. This results in documented efficiencies that exceed 99.3% at 100 kHz.Ī block diagram of the CleanWave200 reference design.īruce Renouard, Pre-Switch CEO, explains that "the Pre-Switch controller IC analyzes multiple inputs on a cycle-by-cycle basis, making adjustments in real-time to small, forced-resonant transistors, enabling perfect soft-switching in harsh changing environments. The controller includes logic that embodies several advanced self-learning algorithms, allowing it to optimize the shape and timing of each switching pulse. The controller was demonstrated in the CleanWave200, a 200-kW (space vector modulated) evaluation inverter that uses three discrete, low-cost 35-mΩ SiC MOSFETs per switch location.
