2.2.4 Simulation Results
The following section show simulation results to review the expected behavior before discussing the final measurement results. For the simulations a lower load capacitance value of 20-uF was selected in order to minimize run time. The following simulations show results with D2 and without D2 in Figure 2-5. This is a recommended diode to prevent the output from oscillating when the capacitor and inductor are left floating when precharge has been completed. Figure 2-7 shows the maximum switching frequency for the system. Figure 2-6 and Figure 2-8 show simulation with the transient clamping diode and without the transient clamping diode respectively.
