saber仿真:使用uc3845仿不起來閉環(主電路有變壓器)
我現在用uc3845,在仿傳統boost電路時是可以閉環的.但是在仿隔離boost變換器時,也就是比boost電路多了一級變壓器隔離.
閉環后瞬態仿真錯誤提示:
*** ERROR "ALG_NO_SOLUTION" *** Cannot find nonlinear system solution.
*** ERROR "ALG_SINGULAR_JACOBIAN" *** Singular Jacobian matrix.
Some possible causes for a singular Jacobian matrix:
- Model operating outside of its intended region of operation.
- Node/subsystem with no connection to the reference (floating).
- Current loops (voltage sources/inductors in parallel).
- Missing equation and/or missing variable reference.

uc3845很容易出這樣的錯誤.另外,saber上我只看到節點,沒有看到line呀?

提示信息
ERROR "ALG_OUT_OF_REGIONS"
Example
*** ERROR "ALG_OUT_OF_REGIONS *** /op_amp1.ut/tn.q2/pxvbci (q.1) is out of defined sample points on the low end.
Problem
This error is generally associated with the use of the q, spq, d, and spd models, but can also appear when others are used. The voltages and/or the currents applied to the model are outside the defined operating range. Check the error message to determine which models are involved.
Solution
?Check your netlist to make sure the models are connected and biased correctly.
?Find out if the collector-to-emitter voltages are being limited. Use the di command to display DC voltages. Invoke the SaberScope Waveform Analyzer to see tranalysis or dtanalysis results.
?If the error still occurs, contact Customer Support.
按上面的提示檢查一下電路吧!
