4 FAQs about Bus voltage in inverter

Can inverter output voltage exceed DC bus voltage?

Generally, the inverter output voltage cannot exceed the DC bus voltage in conventional inverters. However, with certain topologies and techniques like voltage boosting, it is possible to achieve a higher output voltage than the DC bus voltage.

What is a DC bus voltage?

The DC bus voltage determines the maximum output voltage the inverter can produce. It's a key parameter for designing the power stage of the inverter and for ensuring compatibility with the electrical system it will be connected to. Can the inverter voltage exceed the DC bus voltage?

Why do inverters trip if DC bus voltage exceeds a threshold?

Some inverters will trip or issue an overvoltage fault if the DC bus exceeds a threshold (e.g., 800 V on a 400 V-class inverter). In multi-inverter systems sharing a DC bus, regeneration from one unit can affect others. Solar or battery-connected inverters may have intentionally higher DC bus voltages for MPPT or efficiency reasons.

Why is DC-BUS capacitor important in PV inverters?

In standalone and grid-connected PV structures, DC-Bus capacitor is the extremely important passive component. Harmonics and power factor reduction occur in single-phase PV inverters because the DC bus voltage exhibits a double frequency ripple.
