A novel dual independent control for a quasi Z source inverter driven electromagnetic actuator based energy harvesting system

Abstract

This paper proposes a Z source inverter assisted
electromagnetic energy harvesting system. Electrical and mechanical
components in an energy harvesting system produces
electrical energy when tuned optimally. Adjustment of damping
and resonant frequency is a crucial parameter in operating
an energy harvesting system. This paper proposes a Z source
inverter assisted system, where the independent control freedom
of Z source inverter has been utilized to regulate the
output power. The two key components, damping and resonant
frequency, have been regulated and therefore, an improved
performance of the energy harvesting system has been achieved.
The simulation based validation establishes the effectiveness of
proposed architecture and control under operating conditions of
varying frequency and varying amplitude.
