Проект TIDA-00366 представляет собой базовое решение трёхфазного инвертора мощностью до 10 кВт, в котором использованы сдвоенный драйвер затвора IGBTс увеличенной изоляцией UCC21520, усилитель с увеличенной изоляцией AMC1301 и МК (TMS320F28027). Благодаря использованию для измерения тока двигателя AMC1301, сопряжённого с внутренним АЦП МК, и источника питания с компенсационной обратной связью для драйверов затвора IGBT становится возможным уменьшение стоимости системы. Инвертор имеет защиту от перегрузки, короткого замыкания (в том числе на землю), выхода напряжения за рамки напряжения шины постоянного тока и перегрева IGBT-модуля.

The TIDA-00794 reference design is a temp sensing solution for IGBT thermal protection in HEV/EV traction inverter system. It monitors the IGBT temperature via the NTC thermistor integrated inside the IGBT module. It provides thermal shut down to the IGBT gate drivers once the NTC thermistor temperature rises above the programmed threshold. The design includes the IGBT isolated gate drivers, isolation to the high voltage, NTC signal conditioning, Load resistor, and I2C interface to the MSP430, which enables the design system to run independently under high power ratings.

The TIDA-01255 design is built for isolated CAN communication, which is widely used in automotive environments. In hybrid and electric vehicles (HEV/EVs), a complete high-voltage network is floating with respect to the chassis ground. Isolation is required for the power and communication channels interfaced between floating high- to low-voltage systems. The TIDA-01255 design supports applications with a simple isolated transformer driver to transfer power. This TI Design has a low-transmission delay, which reduces the loop delay and supports higher baud rates of the CAN.
Возможности:

Flexible high-speed CAN communication Low loop delay (typically 136 ηs) to support high-speed arbitration rates 750-mW power transfer with 3-kV isolation ±70-V bus fault protection Compliant with ISO 11898-2 CAN standard

This reference design is an automotive, 400-W, phase-shifted full-bridge converter which generates the 12-V output from a 48-V car battery. The enhanced phaseshifted full-bridge controller implements programmable delays which ensure zero voltage switching (ZVS) over a wide range of operating conditions. The output implements synchronous rectification, which enables fast transient response and a high loop bandwidth. The system regulates 12 V at no load with less than 100 mW of standby power. Pseudo isolation is achieved through a transformer to prevent the 48-V battery from being shorted to the secondary side. The half-bridge gate drivers can withstand a maximum boot voltage of 120-V DC.
Возможности:

Phase shifted full bridge converter over the input voltage of 36V to 60V DC, output power up to 400W Extendable to 500W with heatsinking, easy to customize per customer needs Soft-switching, phase-shifted full bridge using UCC28951-Q1 analog controller, Grade 1 Regulated 12V output with 36V to 60V input and with <100mW standby power at no load Adaptive delay control for high efficiency across load range
