T12

Timer T13

Timer12 compare match starts Timer13 to count.

Timer13 provides a delay for stable current measurement to avoid current ringing, IGBT switch on/off delay and dead time.

Timer13 period match triggers ADC to sample.

All triggering are hardware, no software interrupt needed.


Synchronization between CCU6 & ADC


There are two low-cost current sampling methods

Single DC shunt resistor

¬ Suitable for IPM(Intelligent Power Module)

whose 3 low-side emitters are combined together

¬ Low cost

¬ Limitation in low-speed performance, and 6 sector switching points

¬ Complicated software implementation

Two DC shunt resistors

¬ Cannot be used for the above IPM device

¬ Good sampling current compared with single shunt method

¬ Duty cycle cannot reach 100% because a minimum PWM OFF time is needed for ADC sampling

¬ Simple software implementation


ADC Module- Phase Current Sensing


Each 60 deg SVPWM sector using the same phase compare match (mid-one) to trigger Timer13.

ADC Module- Single Shunt Current Sensing


For 2 shunt R sampling scheme, normal symmetrical SVPWM can be applied.

2-phase current can be sampled when all 3 low-side IGBT/MOSFETs are ON.

Using CC60 compare match to trigger Timer13, when 2 low-side IGBT/MOSFETs are ON.

Using Timer13 period match to trigger ADC sampling


ADC Module- Two Shunt Current Sensing

T13PM

ADC


ADC0: Ch0 & Ch3 started by sequential request source 2, triggered by CCU62 T13PM.

ADC1: Ch0 triggered by ADC0_Ch0 in parallel sampling mode.

Thus, analog conversion sequence as below:

ADC0_ch0 -> ADC1_ch0 -> ADC0_ch3

ADC Module- How to sample 3-phase within shortest time ?

Ttotal < 1.6usec



Vector Computer – CORDIC


We will need to compute the Id and Iq.

Traditional Method for computing Id/Iq

Step 1 – Refer to lookup table for cos

Step 2 – Multiple Ialpha with lookup table value

Step 3 – Refer to lookup table for sin

Step 4 – Multiple Ibeta with lookup table value

Step 5 – Add up both result to obtain Id

Iapha

Ibeta


Vector Computer – CORDIC- Park Transform using CORDIC


Instruction 1 – Setup the CORDIC mode

Instruction 2 – load Z with angle value

Instruction 3 – load X with Ialpha value

Instruction 4 – load Y with Ibeta value, Cordic start automatically

CORDIC will output the result of Id and Iq together

Use CORDIC


Vector Computer – CORDIC- Park Transform using CORDIC


MDU is very useful for some mathematical functions such as UIDIV, LMUL, ULDIV, LShift

ROM contains most valuable MDU-routines which can be called by user

– this saves code space and runtime (no wait-state for ROM access)

Easy integration with KEIL compiler

MDU Library support in ROM only available for devices marked with “M”


Vector Computer – MDU
