Power Supply

Instruments’ LM5113-5A gate drivers were used for rectifier and inverter MOSFETs, providing gate
voltages of V = 5 V and deadtimes of t = 2 ns. Xilinx’s Spartan-6 FPGAs were adopted for the
dr dt
overall control implementation.

The nonlinear model and the numerical algorithm proposed previously were coded in Matlab.
The simulated maps compared with the experimental ones show that the model predictions are
correct over the entire investigation range. Three operating conditions that were selected are:
D = 1, φ ÷ π = 0; D = 0.68, φ ÷ π = 0.19; and D = 0.52, φ ÷ π = –0.29.
