“…Note that the term "interval" in Figure 1c denotes the time to set the This paper uses a four-bit digital active gate driver, whose value of R is 1 Ω. The control signal to the driver is generated by a custom-developed Field Programmable Gate Array (FPGA) board, called a universal smart power module (USPM) controller [26]. It adopts a Zynq UltraScale+ MPSoCs chip (XCZU3CG-xSFVC784E, Xilinx), of which the main control clock frequency is set at 400 MHz.…”

This paper experimentally validates a fully digitalized active gate driver for suppressing the switching surge voltage of SiC MOSFETs in a boost converter. High‐voltage power conversion systems are expected to adopt SiC unipolar power devices utilizing their high‐speed switching capability. The high‐speed switching operation causes the switching surge voltage in its switching transient. Active gate driving is a key technology for suppressing it. A fully digitalized active gate driver is particularly focused upon, which freely shaped the output gate‐source voltage waveform by a multi‐bit gate control signal. This driver achieves the dynamical control of the voltage/current behaviours of MOSFET in the switching transient by taking the Miller effect into account. It contributes to suppressing the switching surge voltage. This paper applies this digital active gate driver to a high voltage power conversion circuit. The switching surge voltage is experimentally suppressed by slew rate control with the digital active gate driver for various operating conditions. The results clarify the control strategy of the digital active gate driver for SiC MOSFET in a power conversion circuit.

A universal smart power module (USPM) has been studied as a modularization method for rapidly developing power converters with various specifications. Herein, a control method is proposed for a three-phase modular multilevel converter composed of USPMs. The autonomous balance control of the proposed control method suppresses the variation in the voltage of the cell capacitor and the disturbance caused by communication delays. This enables the application of the proposed versatile extension method. Moreover, current droop control suppresses the effects of delay variations caused by wireless communication and eliminates system instability caused by control interference between modules. Based on the experimental results of steady-state and load-fluctuation responses with a simulated wireless communication implementation, the deviation from the command values of the line and cell capacitor voltage is less than 5%. Furthermore, the autonomous balance control improved the variation in the capacitor voltage in all modules from 9.70 V to 1.94 V. The results validate the effectiveness of the proposed control method in wireless communication environments.
