CRE NEW ENERGY will exhibit at Electronica 2026 in Munich, Germany, from November 10–13 at Hall A6, Booth 353. Discover the DKMJ-S DC-Link capacitor series for high-power conversion, MKMJ-S pulse capacitors for high-energy discharge systems, and DEMJ-PC pulse capacitors for automated external defibrillators (AEDs). Meet the CRE team to discuss film capacitor solutions for inverters, renewable energy, rail traction, industrial pulse-power systems and medical electronics.
In a resonant converter or induction-heating supply, a capacitor may carry a large alternating current while the input power appears modest. That is why ESR deserves attention early in the design.
Resonant capacitors are central to the performance of high-power LC networks. In an induction heater, resonant converter, inverter, or switching power stage, they repeatedly exchange energy with an inductor rather than simply smoothing a DC rail. That makes capacitance only one part of the decision.
Resonant Capacitors are essential to efficient power conversion because they exchange energy with inductors at a controlled frequency. Rather than simply smoothing a DC bus or absorbing an occasional transient, they become part of the main power-transfer path.
IGBT Snubber Capacitors are selected to control the voltage overshoot and ringing that appear when an IGBT commutates current in a real, inductive power loop. The task is not simply to choose the largest capacitance or the highest voltage rating.
