The three-phase bridge on the left, on the PDD205A1121  hand, is fed from the battery to the motor through the three-phase bridge, and on the other hand, during charging, it uses the internal inductance of the motor to create a PFC topology with 4 bridge arms/totem poles (note that the DC voltage is 500V, and the battery voltage is 700V)
At the rear stage of the DC bus, the low-voltage battery can be charged through the full bridge LLC;
What is interesting here is the mirrored full bridge LLC, Q5/Q6/Q7/Q8 and Q9/Q10/Q11/Q12. The waiter understands that the left full bridge is used for energy recovery during braking; The full bridge on the right is the charging circuit for normal battery power supply;
In the patent, BYD actually proposed different other topologies, and those interested can download and research them themselves.

Looking back, under the drive of high PDD205A1121  and low cost, the future multi in one electronic control MCU is being considered:
Is there a dedicated nuclear system for safety monitoring, as multi-core systems are standard equipment?
More computing power, more advanced control algorithms, and improved energy efficiency (in conjunction with third-generation semiconductors)
Higher performance peripheral integration, such as the integration of rotary transformer interfaces, and higher speed communication ports such as CAN FD/XL or FlexRay
High PDD205A1121  PWM is required. If it is multi in one, MCU may need to support PS level PWM. TI’s 28379 supports 150ps HRPWM
