Part Number: TMS320F28027
Other Parts Discussed in Thread: C2000WARE
Hi team,
Here're few questions may need your help:
1) How to control the voltage output and current of buck, boost, and push-pull power supplies?
2) The push-pull boost power supply uses the TMS320F28027 chip to control the generation of two PWMs, a 48-V battery pack using 4 cells as the primary source for the push-pull, a boost to DC 750 V, and a bus supply to the inverter. In the case of inverting changes, the PWM transmits almost no waveform at low load currents and the bus voltage is stable while there will be more waves at heavy loads. What is the control principle and mechanism here?
The push-pull wave is as below:
Could you help check this case? Thanks.
Best Regards,
Cherry
