Inverter, servo motor driver

The input end of the power supply is rectified and filtered to provide a smooth DC power supply to the subsequent load. At the same time, it absorbs the self-induced pulse spike voltage generated by the motor, absorbs the ripple current generated by the inverter circuit, and suppresses high-frequency electromagnetic interference. It is suitable for occasions with high requirements on size.

Photovoltaic inverter

Connected in parallel at both ends of the positive and negative poles of the solar cell, it absorbs the ripple current generated by the high-frequency conversion circuit in the subsequent stage, and suppresses high-frequency electromagnetic interference.

DC-DC converter output filtering to provide a smooth DC power to the subsequent stage load, meanwhile absorbing the ripple current generated by the inverter circuit.

Charging pile

The input power terminal PFC circuit filters to provide a smooth DC bus voltage, absorb the ripple current generated by the subsequent high-frequency conversion circuit, and suppress high-frequency electromagnetic interference.

High-frequency filtering on the output side provides smooth DC power to the subsequent load (lithium battery).

Measures: 1. Improve the tailing paper setting of the rolling machine, so that the tailing paper in the outer ring of the core package is reduced from the original package to a tailless paper. 2. Reduce the diameter of the rolling needle of the rolling machine, and change the diameter of the rolling needle (4.0mm or 5.0mm) commonly used on the rolling machine to 3.5mm. 3. The cathode foil uses 4VF pressurized cathode foil, and at the same time, it uses a foil design to increase Withstands large ripple currents.

product advantages

The volume of the new product has been reduced by about 16% to 28%, but the capacity has increased by 20% to 50%. For customer design, when the design requires a large capacitance and the design space for the passive component of the PCB is small, we can still meet the customer's needs through size reduction.

Through technical improvement and improvement of capacitors from the aspects of equipment improvement, product structure, material matching, etc., the capacitor's ability to withstand large ripple current and reliability have been improved, meanwhile the volume has been reduced;It meets the performance requirements of capacitors for specific circuits such as drivers and inverters, and provides a better solution for customers who have resistance to current surge and size requirements.
