Abstract EN
Nowadays, most three-phase, “off the shelf” inverters use electrolytic capacitors at the DC bus to provide short term energy storage.
However, this has a direct impact on inverter lifetime and the total cost of the photovoltaic system.
This article proposes a novel control strategy called a 120° bus clamped PWM (120BCM).
The 120BCM modulates the DC bus and uses a smaller DC bus capacitor value, which is typical for film capacitors.
Hence, the inverter lifetime can be increased up to the operational lifetime of the photovoltaic panels.
Thus, the total cost of ownership of the PV system will decrease significantly.
Furthermore, the proposed 120BCM control strategy modulates only one phase current at a time by using only one leg to perform the modulation.
As a result, switching losses are significantly reduced.
The full system setup is designed and presented in this paper with some practical results.
