High-Power Resonant Capacitor for Induction Heating | China Suppliers & Factory for Medium Frequency Furnaces
Brief description
Series Resonant capacitor used in high-power Medium Frequency Induction Furnace for Silicon Melting or steel melting.
For an efficient solid state power sources for induction furnace, usually have the induction heating load driven at its natural resonant frequency.
The furnace coil and a capacitor form a resonant tank circuit. The metal to be heated in the coil which resulting in shift in the frequency. The resonant tank circuit is returned via frequency control circuit to achieve resonance and to enable maximum power transfer to the load at all time.
Water cooled capacitors features
Water cooled film capacitors are widely used in induction heating systems because they can handle high operating currents. Heat is generated in the components of system mainly through dielectric losses. Heat is also generated at the points of connection between the leads and the dielectric material. This heat is usually referred to as connection losses. Due to the high levels of currents that these components are exposed to, considerable amount of heat is generated. A appropriate internal cooling design is necessary for induction heating used capacitor which is able to enhance its performance as well as its reliability.
- Terminal: brass terminals brazing with copper tube & insulating bushing;
- Protection: pressure switch to control the internal pressure;
- Dielectric: all-film type with high quality impregnating oil;
- Case: textured Mg-Al alloy plate (No painting).
Quality gurantee for water cooled induction heating capacitors
- Fully-automatic winding machine will test each winding core quality before it goes to next process;
- Test of intermediates will happens at welding and assembly step;
- Vacuum impregnation;
- Leakage test;
- Capacitance measurement;
- Loss factor test;
- Dielectric test between terminals;
- Dielectric test between terminals and casing.
How power capacitors work in induction heating system?
In the inductive heating system, the high-power resonant converters require capacitors with high-power density and high-efficiency. The produced heat energy depends on switching frequency selection, Like 1Khz, 2Khz, or 10Khz etc. The induction heating system aim to convert the input AC power to a specific frequency.
During the induction heating process, the harmonic current and power loss are main problems. For comprehensive efficiency improvement, DC filtering capacitors and resonant capacitors are usually applied for the induction heating system. The typical example is IGBT based LC series resonant circuit system. DC Filter capacitors also work as an energy storage component as well as filter part in DC circuit of Induction Heating System.

Frequently Asked Questions
What are series resonant capacitors used for?
They are used in high-power Medium Frequency Induction Furnaces for Silicon Melting or steel melting, driving the induction heating load at its natural resonant frequency.
Why is water cooling necessary for these capacitors?
Due to the high operating currents in induction heating systems, significant heat is generated through dielectric and connection losses. An appropriate internal cooling design is essential to enhance performance and reliability.
What materials are used for the terminal and case of the water-cooled capacitors?
The terminals are made of brass brazed with copper tubes and insulating bushings, while the case is constructed from a textured Mg-Al alloy plate without painting.
How is the quality of Flair induction heating capacitors guaranteed?
Quality is maintained through fully-automatic winding tests, intermediate welding and assembly tests, vacuum impregnation, leakage tests, capacitance measurement, loss factor tests, and dielectric tests between terminals and casing.
What is the role of DC filter capacitors in induction heating systems?
DC filter capacitors work as energy storage components and filter parts in the DC circuit of the induction heating system to improve efficiency and reduce harmonic current and power loss.
Brief description
Series Resonant capacitor used in high-power Medium Frequency Induction Furnace for Silicon Melting or steel melting.
For an efficient solid state power sources for induction furnace, usually have the induction heating load driven at its natural resonant frequency.
The furnace coil and a capacitor form a resonant tank circuit. The metal to be heated in the coil which resulting in shift in the frequency. The resonant tank circuit is returned via frequency control circuit to achieve resonance and to enable maximum power transfer to the load at all time.
Water cooled capacitors features
Water cooled film capacitors are widely used in induction heating systems because they can handle high operating currents. Heat is generated in the components of system mainly through dielectric losses. Heat is also generated at the points of connection between the leads and the dielectric material. This heat is usually referred to as connection losses. Due to the high levels of currents that these components are exposed to, considerable amount of heat is generated. A appropriate internal cooling design is necessary for induction heating used capacitor which is able to enhance its performance as well as its reliability.

How power capacitors work in induction heating system?
In the inductive heating system, the high-power resonant converters require capacitors with high-power density and high-efficiency. The produced heat energy depends on switching frequency selection, Like 1Khz, 2Khz, or 10Khz etc. The induction heating system aim to convert the input AC power to a specific frequency.
During the induction heating process, the harmonic current and power loss are main problems. For comprehensive efficiency improvement, DC filtering capacitors and resonant capacitors are usually applied for the induction heating system. The typical example is IGBT based LC series resonant circuit system. DC Filter capacitors also work as an energy storage component as well as filter part in DC circuit of Induction Heating System.

Frequently Asked Questions (FAQ)
What are series resonant capacitors used for in induction systems?
They are used in high-power Medium Frequency Induction Furnaces for Silicon Melting or steel melting. They help drive the induction heating load efficiently at its natural resonant frequency.
Why is water cooling necessary for film capacitors in induction heating?
Because these capacitors handle very high operating currents, significant heat is generated through dielectric losses and connection losses. An internal water cooling design is essential to dissipate this heat, ensuring reliability and performance.
What quality control tests do Flair capacitors undergo?
The production process includes fully-automatic winding core tests, welding and assembly intermediate tests, vacuum impregnation, leakage tests, capacitance measurement, loss factor tests, and dielectric tests between terminals and casing.
How do DC filter capacitors function in an induction heating system?
DC filter capacitors function as energy storage components and filtering parts in the DC circuit. They work alongside resonant capacitors to reduce harmonic currents, minimize power loss, and improve overall system efficiency.
What are the case and terminal materials of these water-cooled capacitors?
The terminals are made of brass brazed with copper tube and insulating bushings. The case is constructed from unpainted textured Magnesium-Aluminum (Mg-Al) alloy plate or patterned aluminum sheet.
