Beschreibung
This reference design highlights an ultra-low standby isolated AC/DC auxiliary power stage followed by converters and linear regulators, a comparator-based control pilot interface to meet the SAE J1772 standard, an efficient relay and contactor drive and isolated line voltage sensing across the relay and contactor. Electric vehicle service equipment (EVSE) facilitates power delivery to electric vehicles safely from the grid. An EVSE control system consists of an auxiliary power stage, an off-board AC/DC high power stage (only in DC charging stations), energy metering unit, AC and DC residual current detector, an isolation monitor unit, relays and contactors with drive, two-way communication over single wire, service and user interfaces.
Eigenschaften
- Ultra-low standby UCC28740-based isolated AC/DC stage to achieve ENERGY STAR® certification for EV charging stations
- Tight output voltage regulation (< ±2%) of LDOs and the high slew rate of the TLV1805 device ensures SAE J1772 certification for the control pilot interface
- Ultra-low standby as well as cost-optimized converters and linear regulators to power up points-of-load
- DRV110 current controller to drive high-current relays and contactors for thermal protection and reducing power dissipation
- Isolated line voltage sensing using the ISO1212 digital-input receiver for welded relay and contactor detection
Typische Anwendungen
- AC charging (pile) station
