The SECO-1KW-MDK-GEVK is a complete reference design for three-phase motor drives, featuring the NFAQ1060L36T intelligent power module in a DIPS6 package, and part of the Motor Development Kit (MDK). Rated for 230 Vac input and delivering up to 850W. All the necessary system blocks for a motor drive are part of the solution: EMC filtering and rectification stage, interleaved two-channel PFC, auxiliary power supplies, three-phase inverter and measurement and protection.

The MDC901-EVKHB evaluation kit gives power designers a head start for design-in of the MDC901 200V GaN gate driver. The evaluation board (EVB) utilizes GaN System’s 100V enhancement mode HEMTs and Würth Elektronik components in a half-bridge configuration. The kit provides complete out-of-the-box testing capabilities for quick implementation. At a PCB size of 80x90mm², the evaluation board is compact and is accompanied with all required components to directly begin testing.

The device is a full bridge motor driver intended for a wide range of automotive applications. The device incorporates a dual monolithic high-side driver and two low-side switches.Both switches are designed using STMicroelectronics’ well known and proven proprietary VIPower®M0-7 technology that allows to efficiently integrate on the same die a true Power MOSFET with an intelligent signal/protection circuitry.

This IC outputs the AC voltage zero cross timing detection with high accuracy. By eliminating the need for photocoupler and external components required in conventional applications, it is possible to reduce the number of parts drastically and realize compact and highly reliable power supply applications. In addition, this IC can reduce standby power largely in comparison with an existing photocoupler control.
