Hi, below is a AC-AC frequency converter with a step down voltage from 200 to 20 Volts
Question: As you can see that the efficiency is 1.55/2.251 which is about 66%. May i know how to improve the efficiency of this circuit. I have tried to change the capacitance of capacitor since it absorbs a lot of power, however, if you reduce it too much, a lot of ripple will form which causes the frequency converter at the next circuit to be inefficient. Would be glad if anyone can offer me some guidance. I have post my LT Spice file below, try to simulate it and maybe offer some correction. I know that the voltage are too high for capacitor can handle but let's just forget about that now because I can adjust it. Thank you
