I was trying to drive this transducer in the image (with H-bridge and LC filter circuits behind it). However, after simulating the whole circuit, the running began and continued very long time and simulation gave meaningless plot. How can I solve this problem? Because of the company policy I can not share the whole circuit. Also, input of the transducer is 250-300 Vpeak with 0V offset. And load resistance, which corresponds resistance of transducer, must be approximately 50ohms. In other words, transducer is load and has 50 ohms resistance. Also, values of the components are not exactly the same as with the real circuit, because of company policy I changed them.
Thank you for your consideration
