IEEE International Future Energy Challenge

The International Future Energy Challenge is an annual undergraduate student competition in the design of power electronic systems. The competition topic and location change every year.

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

Specification

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

Prizes:
There will be a Grand Prize of $10,000 and three additional awards granted at $5,000, $3,000 and $1,000 each. Competition metrics will include design considerations, measurement results, and innovation.
