Abstract :
This paper presents two new inverters that impose voltage on the load. The topologies are based on two current sources feeding each inverter phase alternately, allowing load voltage control, employing only two high frequency switches. The voltage imposition on the capacitor is done through the implementation of a double hysteresis control circuit. The reference waveforms are generated by a microprocessor. The operating principle, control strategy, simulated and experimental results are presented
