A Non-Isolated Buck-Boost Grid-Connected Inverter with no Shoot-Through Problem

Abstract:

The grid-connected inverters required for distributed generation systems should have high reliability. However, a shoot-through problem, which is a major killer of the reliability of the inverters, exists in the conventional bridge-type voltage-source inverters. In order to solve the aforementioned problem, a non-isolated buck-boost grid-connected inverter with no shoot-through problem is proposed. The hysteresis current control is used. The output voltage of the proposed grid-connected inverter can be larger or lower than the input voltage. The operating principle is illustrated. Simulation verifies the theoretical analysis.
