A Novel DC-DC Boost Converter for Piezoelectric Actuators in Automotive Applications
S. Sivaram
Abstract: In this paper, a novel high step-up converter is presented for piezoelectric actuators, which uses one coupled inductor with small turns ratio. This converter produces an output with high voltage gain with small component design. The switches used here are operated at zero voltage switching, hence efficiency is improved. Aside from this the converter produces a non-pulsating current, which reduces the current stress across the output capacitor and also output voltage ripple. The simulation is done in PSIM software which produces 110 V output voltage and 120 W output power. The input supply is 12 V and the switching frequency is 5 KHz. The simulation results are provided which highlights the merits of the proposed work.
