Abstract: This paper is to present a new space vector PWM algorithm for four- switch three-phase inverters
(FSTPI) under DC-link voltage imbalance in Photovoltaic or Fuel cell - inverter technology. By using
reasonable mathematical transform, Space Vector PWM technique for FSTPI under DClink voltage
imbalance or ripples have been solved, which is based on the establishment of basic space vectors and
modulation technique in similarity with six-switch three-phase inverters. This approach has a very important
sense to solve hard problems for FSTPI under DC-link voltage imbalance, for example ensuring the required
referenced voltage for undermodulation mode and overmodulation mode 1, 2 to sixstep mode. Matlab/
Simulink is used for the simulation of the proposed SVPWM algorithm for undermodulation,
overmodulation mode 1 and 2. This SVPWM approach is also validated experimentally using DSP
