CRE New Energy achieves mass production of fully domestic 3.6 mF/4 kV DC-Link capacitors, supplying the 220 kV Tianhe–Tangxia flexible DC project and delivering 900 MW of reliable power to central Guangzhou.

In power electronic systems, fast switching and stray inductance often create voltage overshoot, ringing, and electromagnetic disturbance. A snubber resistor‑capacitor (RC) network – containing a dedicated snubber capacitor – absorbs transient energy, controls switching waveforms, and protects IGBTs

● Induction Heating Capacitors are essential in industries that use high-frequency or medium-frequency induction heating. ● Metal hardening, brazing, forging, melting, and casting devices are among the most common application areas. ● Capacitor performance influences resonance, thermal stability, current handling, and circuit performance. ● Water Cooled capacitor designs are widely used in continuous-duty and high-current industrial systems. ● In heavy industrial voltage systems, capacitor reliability affects both production consistency and equipment life. ● Industry demand is strongest where induction heating requires repeatable output, localized heating, and stable operation over long cycles.

Capacitors are not high-pass filters by themselves, but they are essential to high-pass filtering because their reactance decreases as frequency increases. This allows them to block DC and pass higher-frequency signals in the right circuit. The same behavior also makes capacitors important in coupli

● Induction heating provides fast, localized, and non-contact thermal processing. ● Its disadvantages include higher equipment cost, cooling demand, and circuit complexity. ● Induction Heating Capacitors are essential for resonance tuning and power transfer. ● Water-cooled capacitor designs are common in high-current induction heating systems. ● Capacitor quality influences efficiency, thermal stability, and operating frequency. ● Industrial applications include hardening, brazing, melting, forging, and casting.

As AI infrastructure scales to 800V and 1 MW power densities, MKP film capacitors are increasingly critical for ensuring 100,000-hour system reliability in high-stress environments. CRE offers a range of power stage components designed for these high-performance applications: the DMJ-MC for DC-link smoothing, the DMJ-PS for compact inverter designs, and the SMJ-P for snubber protection. These MKP film capacitors feature low ESR/ESL and self-healing properties to help minimize switching losses and withstand high-transient conditions.
