This three-phase, compact power stage reference design for industrial drives, which uses a UCC53xx gate driver to support basic capacitive isolation requirements, provides an increased lifespan and better propagation delay match over optocouplers to minimize inverter deadband distortions and losses. If required, another level of basic isolation can be used between the controllers to achieve reinforced isolation at the system level. This approach optimizes the isolation cost of the system and adds an added benefit of compactness. This design also demonstrates the interlocking feature of the gate driver, which protects the IGBTs during shoot-through. This reference design uses the F28379 Delfino control card to generate PWM signals for controlling the three-phase inverter.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
