Capacitors of GTO & IGBT protection for power electronics. Series P01F
 |
Damping capacitors are mainly used in the following areas:
- Thyristors protection;
- protection of gate turn-off thyristors (G.T.O.);
- Clipping (secondary damping).
The main task of damping RC circuit is “extinguishing” voltage impulses that arise at the moment of switching inductive loads on thyristor’s or power transistor’s connection terminals. As it is known, self-induction force arises at the moment of chain interruption, containing sufficient inductive loads (electric motors, transformers, etc.).The peak value of self-induction force is several times higher than operating voltage and it depends on the speed of chain interruption or switching frequency, this fact is topical for modern equipment with pulsed power regulation.
The given below diagrams show the power that arises between thyristor’s connection terminals (the upper part of the diagram) and connection terminals of inductive loads (the bottom part of the diagram) while working.
The 1st diagram shows thyristor’s operating voltage without damping RC circuit. It is clearly delineated a so called power “thorn” when a thyristor is locked.
The 2nd diagram shows the voltage, when a thyristor works in the same mode, but with damping RC circuit.
The schemes are given for the supply voltage 220 V 50 Hz, a thyrister is open a quarter period.

General description
Production is based on a “dry” technology where the metallized polypropylene film with self-healing is used. And the special composition of polymeric dielectric enables to reach high dielectric strength in the temperature range up to +85°C.
PO1 capacitors have an extremely low resistance in series and induction coefficient (from 5 nH to 20 nH), and such capacitors can be applied to connection diagram with high frequencies and high operating current.
Case
Self-extinguishing plastic case is filled with resin that meets RoHs requirements (according to UL 94).
Self-extinguishing polyurethane resin (according to UL 94).
Connection terminals:
Round axial-lead electrodes with screws M8 placed on both sides of a capacitor’s case.
STANDARDS
Our capacitors meet the following standards:
- IEC 61071: Power electronic capacitors;
- IEC 60068-1: Environmental Testing;
- IEC 60077: Railway applications Electric equipment for rolling stock Part;
- UL 94: Plastic flammability testing;
- IEC 61881- Ed.2: Railway Applications - Rolling Stock Equipment - Capacitors for Power Electronics.
