Method of reducing current collapse of power device |
摘要 |
According to example embodiments, a method of operating a power device includes applying a control voltage to a control electrode of the power device, where the control electrode is electrically separated from a source electrode, a drain electrode, and a gate electrode of the power device. The control voltage is separately applied to the control electrode. The method may include applying a negative control voltage to the control electrode prior to applying a gate voltage to the gate electrode. |

1. A method of operating a power device to reduce current collapse due to electrons trapped in a channel supply layer when the power device is changed to a turned-on state from a turned-off state, the method comprising: applying a control voltage to a control electrode of the power device, the control electrode being electrically separated from a source electrode, a drain electrode, and a gate electrode of the power device, the control voltage being separately applied to the control electrode; applying a gate voltage to the gate electrode, the applying the control voltage to the control electrode includes detrapping the electrons trapped in the channel supply layer by applying a negative control voltage to the control electrode, and the applying the negative control voltage being performed prior to the applying the gate voltage, and a duration of the applying the negative control voltage overlaps a duration of the applying the gate voltage; and applying a bias voltage of about 0 V to about −20 V to the control electrode when the power device is in the turned-off state, an absolute value of the bias voltage being smaller than an absolute value of the negative control voltage. |
