Title:
Power converters, power generation systems, controls and power conversion methods
Document Type and Number:
Japanese Patent JP6295782
Kind Code:
B2
Abstract:
A power converter (2; 2A; 2B; 2C) according to embodiments includes a boost circuit (10), a single-phase inverter (11), a current controller (22; 22A), and a power conversion controller (23; 23B). The current controller (22; 22A) generates a voltage reference based on a difference between current output from the single-phase inverter (11) and a current reference. The power conversion controller (23; 23B) controls the single-phase inverter (11) to generate a first portion of the AC voltage, and controls the boost circuit (10) to generate a second portion of the AC voltage. The first portion corresponds to the voltage reference of which an absolute value is smaller than the voltage of the DC power supply (3). The second portion corresponds to the voltage reference of which an absolute value is greater than the voltage of the DC power supply (3).
