This reference design provides a design template for implementing a three-level, three-phase, gallium nitride (GaN) based ANPC inverter power stage. The use of fast switching power devices makes it possible to switch at a higher frequency of 100 kHz, reducing the size of magnetics for the filter and increasing the power density of the power stage.
The inverting buck-boost is a popular non-isolated, inverting power stage topology. Power supply designers choose the inverting buck-boost power stage because the output voltage is inverted from the input voltage, and the output voltage can be either higher or lower than the input voltage.
A switching power supply consists of the power stage and the control circuit. The power stage performs the basic power conversion from the input voltage to the output voltage and includes switches and the output filter. This application report addresses the inverting buck-boost power stage only and does not cover control circuits.
With the thermal impedance information of the thermal system design, the proper device rating can be selected. The 1200-V/75-mΩ SiC MOSFET and 650-V/60-mΩ SiC MOSFET is a good tradeoff among thermal, efficiency and cost. The primary source of lost efficiency in any inverter is going to be a result of the losses incurred in the switching devices.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
