Among the various current control techniques, hysteresis control is the most popular one for voltage source inverter. As the photovoltaic arrays are good approximation to a current source, most of photovoltaic inverters are voltage source inverters.
Single Phase Inverter The basic hysteresis current control is based on an on-line PWM control that fixes the output voltage of the inverter instantaneously. The main task of the PWM current controller in an inverter is to adjust the output current, i, in order to track the current reference provided by i*.
1. Introduction Hysteresis inverters are used in many low and medium voltage utility applications when the inverter line current is required to track a sinusoidal reference within a specified error margin. Line harmonic generation from those inverters depends principally on the particular switching pattern applied to the valves.
The bang-bang action delivered by the hysteresis-controlled inverter, therefore, drives the instantaneous line current to track the reference within the relay band (− ε, ε).
