Power-over-Fiber for Power Electronics

Commercial and industrial use of high-voltage, high-power-density conversion systems is expanding. Applications include high-speed motor drives, down-hole drilling, EV-chargers, inverters for wind and solar, circuit breakers, and ultimately, solid-state transformers. By 2030, it has been estimated that more than 75% of all electric power will flow through power electronics systems. To meet the higher power demand, higher voltages are preferred over higher currents due to weight and resistance effects. Wide bandgap (WBG) power modules made from materials such as SiC offer the most promising solution. However, the switching frequency of present 10-kV SiC MOSFETs is limited to 1kHz by parasitic capacitance and EMI stemming from conventional isolation transformers. Replacing the inductively coupled power source for gate-drive circuitry by power-over-fiber eliminates the parasitic capacitance and EMI enabling more than a 10-fold increase in switching frequency. In this paper, the fundamentals of power-over-fiber for power electronics will be presented. Examples of longstanding and reliable power-over-fiber applications in instrument transformers and optical probes with CMRR values up to 160dB will also be covered.
