Mark,
Fundamentally , the resolver implemented in TIDM-02009 is similar to the above image. There are a few differences but they do not affect the below explanations. Basically, the closed-loop transfer function of the PLL loop is of the form of a second…
Gokhan G. said: 1) In TIDM-02009, why is there need to add additional OPAMP circuit to the rectified signal. It can be provided directly to the ADC pin. Is it done to protect ADC from negative signal during reverse mode of operation? However, in this case…
Part Number: TIDM-02009 Other Parts Discussed in Thread: TIDM-BIDIR-400-12 Customer would like to evaluate the bidirectional DCDC solution (400V-->48V). The latest one should be bidirectional PSFB in TIDM-02009, right? Is there any materials to introduce…
Part Number: TIDM-02009 Other Parts Discussed in Thread: TIDM-02000 , SFRA Hi,
I'm trying to understand how DF22 parameters are calculated and also what is the used crossover frequency and gain margin.
Outer loop parameters are as below;

Part Number: TIDM-02009 Other Parts Discussed in Thread: TIDM-02000 Hi Ti Support Team,
We are interested in the HV/LV DC/DC
Can you tell us what frequency you are switching at, how is the efficiency, and for which input and output voltage range the DCDC…
Part Number: TIDM-02009 Hi,
I'm investigating the schematic of TIDM-02009.
1) I couldn't find the main transformer part number and its related design document. Could you please share them?
2) What is the Volt.usec of main transformer for only…
Part Number: TIDM-02009 Other Parts Discussed in Thread: TIDM-02000 Hi, I'm investigating the schematic of TIDM-02009.
1) What is the purpose of current transformer at below figure? Is it for protection or current mode control or boost mode current…
Part Number: TIDM-02009 Hi,
In TIDM-02009, the delay for computing 4 successive conversions of the same ADC channels is given as:
motor1.resolverCompDelay = motor1.sampleTime - ( ADC_S_H_TIME_NS / 2.0f + ADC_CONV_TIME_NS + (ADC_S_H_TIME_NS * 4.0f +…
