A diode voltage measurement system includes a plurality of diodes connected in series along a single line. The plurality of diodes include N diodes. The system includes a plurality of capacitors for at least N−1 of the diodes. Each capacitor is connected in parallel to the single line with a respective diode to form a respective diode-capacitor (DC) pair. Each DC pair is configured such that each DC pair reaches a steady state voltage at a different time. The system includes a current supply connected to the single line to supply a current to the line. The system includes a control module configured to sense a total voltage across the single line and to successively determine voltage of each diode from the total voltage based on the current, a known total steady state voltage, and known time-to-steady-state-voltages of each DC pair and/or diode.
