Battery Boosted Charging
Overview
Active Front End Rectifier (AC/DC)
User defines output DC voltage and current limit. Regeneration to AC source will occur if the DC link voltage is above the target dc voltage setpoint.
Boost Converter (DC/DC)
User defines high side DC output voltage and current limit. The converter will control amplitude and polarity of current to regulate the voltage setpoint.
Buck Converter (DC/DC)
User defines low side DC output voltage and current limit. The converter will control amplitude and polarity of current to regulate the voltage setpoint.
Inverter (DC/AC)
- Support single, split, and 3-phase operating modes.
- Grid-Forming Mode: User defined desired voltage, frequency, current limit, and phase angle offset.
- Paralleling Mode: User defined nominal voltage, frequency, and current limit. The inverter will regulate to the nominal AC bus voltage and track shifts in frequency. Units in parallel share the load equally if no additional power setpoint command is given.
To push or pull power from the grid, the inverter can increase/decrease its voltage setpoint based on a desired power level and or lead/lag the nominal microgrid frequency.
Active Neutral (DC/DC)
The converter output will be ½ of the input voltage. This is used to generate a mid-point reference voltage needed in many AC systems. The neutral line is used as a return in single phase AC systems and to return any unbalanced current in multi-phase systems. It can also be used in electric vehicles where they need a mixed 800V and 400V high voltage rails during fast charging. The converter will control amplitude and polarity of current to regulate the voltage setpoint.
