WebIn the MATLAB/Simulink environment, a 2S-2L-based buck-boost converter (see Figure 1) is designed.For the steady-state analysis., the inductors in the proposed converter are assumed to be working in CCM. The values of the inductors and capacitors are calculated using the theoretical analysis described in section II and the equations (), (), (), and … WebFor example, for a 24V to 5V conversion, there is a duty cycle of VOUT / VIN = 0.208, meaning the HS-FET conducts the inductor current only 20.8% of the time. This means the conduction loss only adds up to 20.8% of the total conduction losses.
WebAn inductor, which stores energy, limits the current slew rate through a power switch. The energy stored in the inductor can be expressed in joules as a function of the current with: E = 1/2 X L X I2 Inputs Input Voltage V Output Voltage V Output Current mA Output Voltage Ripple Factor mv (pp) Operating Frequency kHz Output Timing Capacitor (Ct) WebCurrent Rating for Switch in Buck Converter. The current rating for a switch is calculated based on average current. By drawing the switch current waveform, the average value …
