Please refer to the photo of the attach H-bridge circuit below.
Currently, we are using the H-bridge as a drive circuit for the series RLC resonance circuit (not the motor!). Because of this, we probably won't need LTV-827 there to electrically isolate the H-bridge.
Because we need it to run around 80 ish kHz, and the TA said we need to add BJT there because we have high voltage ( 140 V rms )across the capacitor of RLC circuit.
Just wondering do you guys understand why should add BJT and what effect will it bring to the circuit?
