Product overview
Description
This 50 kW T-type DC/AC inverter reference design introduces a complete ST’s digital power solution for high power three-phase DC/AC inverter applications based on the three levels T-type topology. This reference design topology is mostly used for industrial photovoltaic (PV) solar applications and commercial energy storage applications.
This reference design achieves larger than 98.89% peak efficiency by utilizing ST’s 1200 V, 9.5 mΩ and 750 V, 6 mΩ T-type SiC module, which is in a ACEPACK2 package. It features fully digital control, with the STM32H743ZG mixed-signal high-performance microcontroller providing full control of the output power and the task to manage the grid connection procedure. It provides high bandwidth continuous conduction mode (CCM) current regulation for maximum power quality in terms of total harmonic distortion (THD) and power factor (PF).
