我做了一個UC3854的仿真電路,仿真電路如圖所示,電路倒是能夠運行仿真,但是怎么仿不出結果呢?
各位高手請指點。出錯信息如下:

The no_ramping algorithm failed. Trying the dyn_ramping algorithm.

*** 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.

圖中的快恢二極管是STTA1206D,而不是1N4148,我沒有改過來,不好意思
