2.6.2  Simulation of a three-stage cascade

Figure 2.10 shows the schematics of a three-stage voltage multiplier. V1 is the alternating voltage source. The MUR1560 are simulation models of ultrafast 600V / 15A rated Diodes.

Figure 2.11 shows the simulation data voltages at the voltage probe markers in Figure 2.10 when charging the smoothing capacitors (C2, C4, C6).

Figure 2.12 shows the simulation data voltages at the voltage probe markers in Figure 2.10 in stationary load-state. The load of 1MΩ generates an output voltage of 594.37V with a voltage-drop of 28mV (0.0048%).

The theoretical output voltage (no load, ideal diodes) is:

Figure 2.13: Voltage multiplier: Voltages, Load = 10kΩ

Figure 2.13 shows the cascade with a load of 10kΩ. The maximum output voltage is 489.3V, the voltage-drop is 26.4V (5.4%)

Figure 2.14: Voltage multiplier: Voltages with  Load = 1kΩ

Figure 2.14 shows the simulation data with a load of 1kΩ. The maximum voltage is 262.3V and the voltage-drop is 85.1V (32.4%).
