我做了一個(gè)UC3854的仿真電路,仿真電路如圖所示,電路倒是能夠運(yùn)行仿真,但是怎么仿不出結(jié)果呢?
各位高手請(qǐng)指點(diǎn)。出錯(cuò)信息如下:

*** 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.
