Three-phase inverter reference design for 200-480VAC drives (Rev. A) This reference design realizes a reinforced isolated three-phase inverter subsystem using isolated IGBT gate drivers and isolated current/voltage sensors.
The three-phase inverter is designed to operate from the DC bus voltage up to 1200 V. This design uses an IGBT module instead of discrete IGBTs. This reference design is intended to support various makes of IGBT modules so a commonly used footprint of IGBT module is selected.
High-end three-phase inverters use ΣΔ modulators for current sensing, which also asks for using expensive controllers with built-in SINC filters. Using an isolated amplifier enables interfacing with low-cost M4 core MCU or TI’s Piccolo with a built-in SAR analog-to-digital converter (ADC).
Aiming at evaluating the output performance of the single three-phase voltage source inverter with LC filter system adopting different MPC strategies when different types of load including two-phase pure resistance load, three-phase nonlinear rectifier bridge load, constant power load and constant current source load are connected to it.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
