TIDM-BUCKBOOST-BIDIR: Implementing Current Mode Control mode in TIDM-BUCKBOOST-BIDIR reference design

Part Number: TIDM-BUCKBOOST-BIDIR
Other Parts Discussed in Thread: TMS320F280049C, TIDM-02000

Dear TI forum , 

The TIDM-BUCKBOOST-BIDIR reference design is a Non-Isolated Bi-direction Buck Boost Converter implementation . 

Here One of the control algorithms is "Maximum power point tracking (MPPT) control, input current control " 

Is there any guidance or reference design [same circuit topology] on how to implement the "current control mode" using the internal CMPSS of the TMS320F280049C mcu ?

The idea is to feed the inductor current directly to the internal comparator via the analog pin mux [ not performing any ADC sampling ] 

Thanks in advance

    Hi Hassin,

    The MPPT is normally used in solar inverter control to get most power out of solar panel. MPPT control is normally the out loop that is implemented in software.

    For CMPSS based current control, you assume you mean peak current mode control. You can take the TIDM-02000 reference design for a example of PCMC implementation.
