STMicroelectronics EVLSTRNG 系列评估板

意法半导体 EVLSTRNG 系列评估板用于在脱机功率转换应用中评估 STNRG388A 数字控制器，这些应用包括 EV 电池充电器、UPS 和数字工业电源。由于 STNRG388A 具有数字内核, 还可以通过便捷的超级终端控制监视、控制和调试 EVLSTNRG 电路板。

EVLSTRNG-1KW Board

The EVLSTRNG-1KW Evaluation Board evaluates the STNRG388A digital controller in offline power conversions. The board has an architecture based on a multiphase interleaved DC/DC converter for applications like EV battery chargers, UPS and industrial power supplies. The EVLSTRNG-1KW uses half bridge Single Active Bridge (SAB) topology and supports more than 1000W of power. This topology balances power through 3 parallel stages and delivers high efficiency by enabling one, two or three stages depending on the load. The STNRG388A power conversion dedicated peripherals (SMEDs) drive interleaved power stages and guarantee correct phase realignment during stage activation and deactivation. A digital core allows for monitoring, controlling and debugging the EVLSTRNG-1KW board via a convenient HyperTerminal control.

EVLSTNRG-170W Board

STMicroelectronics EVLSTNRG-170W Evaluation Board evaluates the STNRG388A digital controller in off-line power conversions. A PFC stage followed by a resonant LLC stage supports up to 170W for applications like digital industrial power supplies. The application supports multiple output rails: a high power 24V (6A) channel for the main application, 1 auxiliary 12V (2A) for the controller and an always-on 5V (2A) standby. The STNRG388A power conversion dedicated peripherals (SMEDs) drive the PFC in transition mode (DCM-CCM boundary) while the resonant LLC is controlled with timeshift control (TSC). The STNRG388A manages two conversion stages and guarantees protections required by the application while implementing advanced anticapacitive protection. A digital core allows for monitoring, controlling and debugging the EVLSTNRG-170W board via a convenient HyperTerminal control.
