clamping diode

In this latter state, the two clamping diode valves complete the current path through the phase.

Some op-amps have clamping diodes on the input that prevent use as a comparator.

This new inverter can avoid extra clamping diodes or voltage balancing capacitors.

The clamping diodes on the inputs are to offer some protection against ESD.

A "real" design would have clamping diodes on each driver output to reduce the overshoot and ringing when the winding is switched off each time.

Each protection module contains a circuit that has primary protection provided by a gas-filled arrester and secondary protection provided by clamping diodes.

When used in this fashion, they are often referred to as clamping diodes or transient voltage suppressors because they fix or "clamp" the maximum voltage to a predetermined level.

The DC capacitor is split into two series-connected branches, with the clamping diode valves connected between the capacitor midpoint and the one-quarter and three-quarter points on each phase.

In a refinement of the diode-clamped converter, the so-called active neutral-point clamped converter, the clamping diode valves are replaced by IGBT valves, giving additional controllability.

Another type of three-level converter, used in some adjustable-speed drives but never in HVDC, replaces the clamping diode valves by a separate, isolated, flying capacitor connected between the one-quarter and three-quarter points.

A common type of three-level converter is the diode-clamped (or neutral-point-clamped) converter, where each phase contains four IGBT valves, each rated at half of the DC line to line voltage, along with two clamping diode valves.
