Features

  • Fully programmable digital signal controller based solution
  • Smooth transition between AC-to-DC and DC-to-AC mode by SW
  • PR controllers to zero the error at the fundamental AC frequency and harmonic frequencies in DC-to-AC mode, steady-state error below 1% for output voltage RMS and THD below 1.5% under linear load condition
  • Capacitor current feedback to suppress LCL resonant
  • Fast and stable DC bus pre-charging with Triac and soft starting for AC-to-DC mode
  • Light-load mode to enable higher efficiency and power factor in AC-to-DC mode
  • Cycle by cycle current limitation is realized with flexible DSC peripherals
  • Protections: OCP, OVP, UVP, OFP, UFP, OTP
  • Highly optimized libraries, RTCESL, help speed development and improve code execution efficiency
