DC-Link capacitors
Capacitors for DC buses in converters, inverters, drives, UPS systems, traction, solar energy, energy storage and AC/DC or DC/AC conversion systems.
Supply of DC-Link capacitors, electrolytic capacitors, IGBT snubber capacitors and power capacitors for demanding industrial applications.
TOT POWER Iberia helps select capacitors for DC buses, filtering, energy storage, transient absorption, compensation, converters, inverters, drives, UPS systems and power electronics equipment.
Industrial capacitors for DC-Link, filtering, snubber circuits, high ripple current, DC buses and energy conversion applications.
Power capacitors are critical components in equipment where it is necessary to stabilise a DC bus, filter ripple current, absorb transients, reduce overvoltage, compensate reactive power or improve the electrical behaviour of converters and inverters.
They are commonly used in variable frequency drives, servo drives, rectifiers, solar inverters, UPS systems, industrial chargers, railway systems, induction equipment, welding equipment, power supplies, test benches, energy storage and industrial machinery.
TOT POWER Iberia supports engineering departments, equipment manufacturers, industrial maintenance companies and technical purchasing teams that need to locate a compatible capacitor, replace an existing reference or study an equivalent alternative.
We select industrial capacitors according to rated voltage, capacitance, RMS current, ripple current, ESR, ESL, dielectric technology, mechanical format, terminal type, service life, operating temperature and mounting conditions.

DC-Link capacitors are used in the DC bus of converters, inverters and drives. Their main function is to stabilise the bus voltage, absorb ripple current, reduce oscillations and provide instantaneous energy to the power system.
They are critical components in applications using power semiconductors such as IGBT, MOSFET, SiC devices, thyristors or diodes, especially where high pulsed currents, fast switching or long-term reliability requirements are present.
Power electrolytic capacitors are used when high capacitance is required in a relatively compact volume. They are common in DC buses, power supplies, drives, chargers, rectifiers and equipment where the total capacitance of the system is a key factor.
Industrial formats with screw terminals, snap-in terminals, radial or axial terminals, and special executions can be studied depending on the application, voltage and mechanical requirements.
Snubber capacitors are used to protect power semiconductors against overvoltage, transients and voltage peaks generated during switching. They are particularly important in circuits with IGBT modules, power modules, fast diodes, thyristors and high-energy converters.
Correct capacitor selection helps reduce electrical stress on the semiconductor, improve switching stability and increase the reliability of the complete power assembly.
The power capacitor category includes film capacitors, metallised polypropylene capacitors and other technologies designed for filtering, resonance, compensation, pulse, high current and industrial applications with demanding thermal and electrical requirements.
This family may include capacitors for AC filters, resonant applications, pulse discharge, compensation, special converters, induction furnaces, welding equipment, renewable energy and test systems.
Power capacitors are used in sectors where electrical energy must be filtered, stored, stabilised or switched reliably.
TOT POWER Iberia supports technical departments, engineering companies, equipment manufacturers, industrial maintenance teams and technical buyers that need to locate an equivalent power capacitor, replace an existing reference or define a solution for a new equipment design.
We can work from an existing reference, photograph, drawing, datasheet or the basic electrical data of the application. This page is focused on product and application, without limiting the proposal to a specific brand.
The more technical data available, the more accurate the capacitor selection or equivalent search will be.
Yes. This page is focused on product and application. TOT POWER Iberia can study power capacitors and compatible alternatives according to the customer's technical data, without limiting the proposal to a specific brand.
Yes. We can study alternatives based on the original reference, photograph, capacitance, voltage, ripple current, dimensions, technology and operating conditions.
A DC-Link capacitor is designed to stabilise the DC bus and withstand ripple currents in converters and inverters. It can be film or electrolytic. Electrolytic capacitors offer high capacitance in a reduced volume, but service life, temperature and ripple current must be carefully reviewed.
It is advisable to know voltage, capacitance, peak current, dV/dt, ESR, ESL, terminal type, mounting distance, associated IGBT module and switching conditions.
Yes. We can study special solutions when enough data is available to define capacitance, voltage, current, frequency, format, terminals, temperature and service conditions.
Film capacitors are usually preferred when low ESR, low ESL, high ripple current, good stability, long service life or robust switching behaviour are required. Electrolytic capacitors may be suitable when a high capacitance value is required in a compact volume.
Send us the reference, photograph, datasheet or working specifications. We will review the most suitable option for your industrial application.
You may indicate the current reference, voltage, capacitance, dimensions, application and estimated quantity. You may also attach a photograph of the capacitor or the equipment datasheet.
