Topic

Isolated DC-DC Converter with Fast Transient Response and Low Noise

  • Input Voltage: 400 Vdc
  • Output Voltage: Programmable 20Vdc~150Vdc (Voltage accuracy: <0.5% @10 PLC aperture time)
  • Output Current: 10Adc max at all output voltage
  • Rated Output Power: 1.5kW@150V, 600W@60V, 200W@20V
  • Transient Response of Load Change (0A ↔ 10A @ 20V, 60V, 150V. Typical rising/falling time of load current is about 20μs): Output voltage recovers within 100μs to ±200mV settling band.
  • Step Response of Output Voltage:
    • 20V→60V→150V: rising time<100us (No Load)
    • 150V→60V→20V→Turn OFF: falling time<1ms (No Load)
  • Load Regulation of Output Voltage: <0.1% @ 20V, 60V, 150V
  • Ripple & Noise of Output Voltage: 200mVp-p/30mVrms @ 20V, 60V, 150V, (Full load, Set oscilloscope with 20MHz Measurement Bandwidth.)
  • Conversion Efficiency (include all power consumptions to sustain the operation of power converters.): Output voltage=150V, >92% (@25% load), >96% (@50% load), >95% (@100% load)
  • Power Density: > 1.6W/cm3
