Model predictive direct power control of energy storage quasi-Z-source grid-connected inverter [PDF]
Archives of Electrical Engineering, 2022 In order to overcome the shortcoming of large switching losses caused by variable switching frequency appears in the conventional finite control set model predictive control (FCS-MPC) algorithm, a model predictive direct power control (MP-DPC) for an ...

Controlling the output voltage frequency response of the auxiliary commutated pole inverter [PDF]
, 2016 The auxiliary commutated pole inverter (ACPI) is a PWM soft-switching topology usually employed for switching loss reduction. This work however investigates how the two traditional ACPI control schemes, fixed- and variable-timing, can shape the ...
