saber仿真:使用uc3845仿不起来闭环(主电路有变压器)
我现在用uc3845,在仿传统boost电路时是可以闭环的.但是在仿隔离boost变换器时,也就是比boost电路多了一级变压器隔离.
闭环后瞬态仿真错误提示:
*** 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.
Potential problem variables/equations:

The dyn_ramping algorithm failed.
uc3845很容易出这样的错误.另外,saber上我只看到节点,没有看到line呀?

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.
按上面的提示检查一下电路吧!
