A control technique for multi-MHz multi-level converters to overcome the conversion ratio non-linearity introduced by the minimum/maximum pulse width constraints of gate-drivers and PWM signal generators is presented. The control capitalizes on the converter architecture to significantly reduce the conversion ratio non-linearity without the need of additional hardware. The technique is implemented on an FPGA and verified experimentally using a 15W, 30V five-level converter capable of operating up to 150 MHz. The results, assessed over a range of 0.5MHz to 5MHz modulating frequency, show that the technique has the potential to reduce the non-linearity distortion by more than 50% without compromising the efficiency.
