What is a parallel inverter system?
Parallel inverter system are designed to have the advantage to increase output power and enhance reliability. It converts the DC power from the battery into AC power to supply to AC appliances.
Why is parallel inverter operation more complicated than direct current power supply?
Parallel inverter operation is deeply studied based on the successful experience of paralleling process. However, the inverter power supply outputs AC varying according to the sine wave law. Therefore, the parallel operation is more complicated than the parallel direct current (DC) power supply, primarily manifested in three aspects.
What is a bidirectional power supply?
A bidirectional power supply demands a different design approach compared to an equivalent unidirectional supply. A unidirectional AC/DC power supply designed for high efficiency uses wide bandgap (WBG) SiC or GaN power devices with a totem-pole power factor correction (PFC) front end driving a DC/DC topology such as an LLC resonant converter.
What is a unidirectional AC/DC power supply?
A unidirectional AC/DC power supply designed for high efficiency uses wide bandgap (WBG) SiC or GaN power devices with a totem-pole power factor correction (PFC) front end driving a DC/DC topology such as an LLC resonant converter. Although the totem-pole PFC topology is bidirectional, the resonant LLC is not.
Do EV charging stations need bidirectional power supplies?
Scenarios that call for bidirectional power supplies in EVs and EV charging stations include: EV supplying power back to the grid or to a microgrid in the home. EV charging station supplying power to an EV either from the grid or from stored energy depending on relative electricity prices.
