“…If the electrolytic capacitor is put at the input, a rather easy servicing is possible. An end of life can be detected by a higher HF ripple or higher temperature [10], In three-phase it can be omitted [11,12]. Also the inductive components can be improved in those topologies [12].…”

Power electronic converters may have a quite long lifetime, but some applications such as converters for automotive and photovoltaic could even desire a longer life. One of the elements to increase the lifetime of converters is to avoid electrolytic capacitors, They can be replaced by metalized film capacitors or ceramic capacitors. A lot of converter types can be redesigned to use them, but it influences the way of designing, as a lower capacitance value is used. Electrolytic capacitors are one of the elements that reduce the lifetime of power electronic converters gradually an adapted design can avoid that electrolytic capacitors have to be used in converters. A range of examples can be shown from fractions of watts up to Gigawatt. For example gate drive circuits, single and three-phase converters where film capacitors are used in the DC link, high voltage DC converters. These techniques are useful to prolong the life of converters and to allow higher ambient temperatures, typical application domains are PV and other grid connected converters, converters for battery charging and general electric vehicle applications.

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.
