I'm seeking a proficient engineer to create a detailed simulation model in LTspice for a Buck-Boost SMPS design. Key Components for Inclusion: - Half-bridge with MOSFETs, where the MOSFETs have built-in antiparallel diodes - Control using a function generator, logic inverter, and high/low gate driver - Both buck and boost modes must be demonstrated - DC link overvoltage protection must shut down the converter if the voltage exceeds 60 V - Power supply with a maximum of 30 V - The converter must deliver/absorb a DC current (on the inductor side) of up to 5 A Ripple voltage on the DC link capacitor (under the worst-case current and output voltage conditions) and on the output capacitor (when the output is unloaded) must not exceed 100 mV peak-to-peak - When calculating the ripple on the DC link capacitor, assume that no ripple current can flow back into the power supply To Design - Gate resistors for the MOSFETs - Bootstrap circuit design, including: - Minimum value and voltage rating of the bootstrap capacitor - Minimum value and voltage rating of the DC link capacitor - Minimum value and voltage rating of the output capacitor - Design and component values for the protection circuit - Identify which circuits need to be built with low inductance - Expected losses in the MOSFETs + diodes and in the inductor under the given conditions - Temperature rise of the MOSFETs at -5 A and +5 A To Measure: - Efficiency as a function of inductor current from -5 A to +5 A, for three different inductor values, each time at a DC link voltage of 30 V - Waveforms of the inductor current and voltage across the output capacitor, including screenshots for the report I look forward to your proposals.
