在中高压应用中，传统的隔离栅极驱动采用双隔离通道分别传输驱动信号和驱动功率，存在信号延迟大、尺寸大和成本高的问题。单隔离通道下驱动信号-功率复合传输，是实现功率模块和驱动系统集成化、低成本、高性能的关键技术。针对现有驱动信号-功率初级复合传输方法中存在信号占空比范围受限、无法双向传输、功率传输不稳定等问题，提出一体化驱动的信号-功率时分复用传输架构及方法，聚焦传输时序、调制方式、实现电路等关键技术，提供高效可靠的设计方案。针对驱动信号在宽范围下高保真传输的要求，深入分析了制约驱动信号传输性能的关键因素，并总结了驱动信号、调制载波及电路带宽三者相互影响的规律，为mW级驱动信号与W级驱动功率复合传输奠定了理论基础。进一步地，采用共享链路型时分复用技术，突破了现有一体化传输中难以在驱动信号全占空比范围下实现驱动电平稳定传输和双向信号兼容传输的关键难题，研制了一款基于隔离反激变换器的一体化驱动器，采用脉冲占空比调制和异步时序正向传输驱动信号与驱动能量，反向采用脉冲幅值调制传输故障信号。样机采用平面印刷电路板PCB（printed circuit board）隔离变压器，尺寸低至20 mm×17 mm×16 mm，驱动信号占空比范围覆盖0%~100%，信号频率最高达100 kHz，实现了驱动信号、驱动功率及反向故障信号的全双工一体化传输。

In medium- and high-voltage applications, the traditional isolated gate driver uses dual isolation channels to transfer the drive signal and drive power respectively, which suffers from a long delay, a large size and a high cost. The single isolation channel with signal-power integrated transmission is crucial for achieving the integration, low cost and high performance of power devices and driver systems. A time-division multiplexing transmission architecture and the corresponding method are proposed to overcome the limitations in the existing elementary signal-power integrated transmission methods, such as limited duty cycle, unidirectional transmission and unstable power transfer, providing an efficient and reliable design scheme by focusing on key technologies including the transmission timing, modulation method and implementation circuit. Aimed at the requirement that the drive signal should be transferred with high fidelity in a wide range, the key factors that restrain the drive signal transmission performance are analyzed in depth, and the laws of interactions among drive signals, modulation carriers and band-width are also formulated, so as to support the transmission of milliwatt-level drive signal and watt-level drive power theoretically. Moreover, the shared-link time-division multiplexing technology is used to address challenges in the stable transmission of drive signals and compatible transmission of bidirectional signals under the full-duty cycle range of drive signals during the integrated transmission, and an integrated driver based on an isolated flyback converter is developed, enabling the forward transmission of drive signals and power by means of pulse duty-cycle modulation and asynchronous timing, as well the reverse transmission of fault signals realized by pulse amplitude modulation. The compact prototype (20 mm×17 mm×16 mm) adopted a planar printed circuit board (PCB) isolated transformer, and the duty cycle range of drive signals covered 0%-100%, with a signal frequency up to 100 kHz. As a result, the full-duplex integrated transmission of drive signals, drive power and reverse fault signals was realized.
