Error amplifier (single op-amp, high gain)

Always verify the model’s dead-time behavior by plotting the output against the ramp. tl494 ltspice

Create a triangular/saw waveform using a behavioral voltage source from time Eosc OSC 0 VALUE V(VOSC) Bdummy VOSC 0 V = sin(2 pi 10000*time) ; simple test waveform (replace with proper RT/CT model) Error amplifier (single op-amp, high gain) Always verify

: Use a Schottky diode like the 1N5822 for efficiency. The Feedback Loop Error amplifier (single op-amp

Oscillator: approximate with a sawtooth generated by an integrator and reset via a behavioral current source Rrt RT_NODE 0 1k ; placeholder for RT connection Cct CT_NODE 0 1n ; placeholder for CT connection

: If the simulation hangs, add a small series resistance (1mΩ) to your capacitors and inductors.
