Implement a Maximum Power Point Tracking (MPPT) Algorithm along with control of DC-DC flyback converter using the C2000™ Microcontroller Blocket. The example uses the Texas Instruments™ Solar Micro Inverter Development Kit along with the Texas Instruments F28069M/F28035 controlCARD.

Implement power factor correction (PFC) using a boost converter with the C2000™ Microcontroller Blockset. The example uses the Texas Instruments F28069M controlCARD with high voltage motor control kit (TMDSHVMTRINSPIN).

Read a position of an absolute encoder using the bidirectional serial/synchronous-continuous (BiSS-C) open protocol in the unidirectional mode. This example implements the BiSS-C protocol using TI C2000 peripherals such as CLB, SPI, ePWM, X-BAR, and GPIO using the C2000™ Microcontroller Blockset.
Control Law Accelerator in DC-DC Power Conversion
Manage the voltage mode control (VMC) algorithm for a closed loop DC-DC power conversion system by using the Control Law Accelerator (CLA). An auxiliary software current protection loop is managed by C2000 CPU. In the TMS320F28379D and similar processor families, the CLAs execute the hard-realtime portions of the algorithm can connect with hardware peripherals such as ADC's and PWM's. The C2000 CPU is better suited for hard real-time portions of the algorithm that require multitasking, handling of asynchronous events, and communication with other cores. While this example extends the DC-DC buck converter developed in the MCUを使用したC2000 DC-DC降圧コンバータ example, the strategy presented can be applied to any design where a resource intensive hard real-time process executes on the CLA and real-time multi-tasking processes run on C2000 CPU.
Network Managed DC-DC Power Converter
Manage the asynchronous network commands to a high-speed, closed-loop DC-DC buck converter control algorithm executing the C2000 processor by using the ARM® Cortex®-M processor. In the TMS320F28388D and similar processor families, the C2000 processors execute the hard-realtime portions of the algorithm and use peripherals, such as ADC and PWM. In contrast, the ARM Cortex-M processor manages the high-level asynchronous communication, such as UDP or TCP, that connect the MCU to external systems. This example implements a technique that extends the DC-DC buck converter in the MCUを使用したC2000 DC-DC降圧コンバータ example. You can apply this technique to any design in which a hard-realtime process executes on the C2000 MCU and a high-level asynchronous communication executes on the ARM Cortex-M processor.
Serially Managed DC-DC Power Converter Using C2000
Use a serial connection to manage a high-speed, closed-loop DC-DC buck converter control algorithm executing the Texas Instruments® C2000™ processor. In most C2000 microcontroller unit (MCU) families, the MCU executes the hard-realtime portions of the algorithm and uses peripherals, such as ADC and PWM. The MCU also includes one or more low-power, serial communication interfaces (SCI) connections. SCI can be used to connect the C2000 MCU to external systems without the need to use other processors, such as ARM® Cortex®-M, for higher level interfaces, such as network UDP or TCP. This example implements a technique that extends the DC-DC buck converter in the MCUを使用したC2000 DC-DC降圧コンバータ. You can apply this technique to any design in which a hard-realtime process executes on the C2000 MCU and requires low-power connectivity using an SCI.
Closed Loop Control of Buck Converter using Hardware-In-The-Loop (HIL) Simulation
Uses hardware-in-the-loop (HIL) simulation to implement the closed loop control of buck converter. The control algorithm requires output voltage feedback, which is then fed to the PI controller. The controller outputs the duty ratio which varies to control the output voltage. For more information, see DC-DC降圧コンバータの閉ループ制御.
