Product Application
On-board charger (OBC) is a device that charges AC power from home or public charging stations to EV chargers. OBC can be a charging pile or a power converter in electric vehicle (EV). Although topology and structure of power converter keeps improving and developing, OBC designers still need to focus on risk of failure during power conversion. Because of that, designers need to put protective components in their designs to solve this problem.
As a professional circuit protective component manufacturer, THINKING products offer over-voltage protection, over-current protection, and over-temperature protection to assist OBC in temperature detection and normal operation.
NTSA series is screw-on type NTC temperature sensor, and it can be fastened with simple screw-on installation. Various terminals (including M3, M4, and M5) are available for this series, and its cable length can be adjusted to satisfy customer’s needs. The product is recommended for applications such as heat dissipation module to sense temperature.
TTC3 series and TTS series are dip type and epoxy bead type NTC thermistors respectively. With small size and bendable leads, the products can be placed on PCB and attached to sensing objects for precise temperature detection.
SCK series is an inrush current limiter, and it reduces impact of charging current to semiconductor device at the moment of electrical connection. Furthermore, its power consumption is lower when comparing with fixed resistor. Ceramic PTC thermistor is another component that offers over-current protection, but its power consumption impact to countermeasure components is lower when comparing with SCK series.
TSM series is SMD NTC thermistor from THINKING, and EIA 0201, 0402, 0603, and 0805 sizes are available for this series. Its small size enables its fast response, and its SMD structure is suitable for automated production.
TVR series is metal oxide varistor from THINKING. The component is with dip structure and high surge protection capability, and it is recommended for high temperature application (125℃) to offer over-voltage protection.
Polymer PTC resettable fuse provides resettable overload protection, and which brings flexibility of easy check. Furthermore, the product is recommended for high current applications because of its low current. Both SMD type and dip type are available to satisfy customer's application needs.
For TVS diode, its precious clamping voltage enables its prompt clamping voltage protection. THINKING provides TVS diodes with complete wattage specifications. Peak pulse power dissipation of its TVS diode products ranges from 200W to 1500W, and their reverse standoff voltage are from 5V to 513V.
Climate change and environmental pollutions bring the trend of electric vehicle replacement of diesel car. Besides, efficiency improvement of battery and energy conversion and government policy speed up EV’s replacement for diesel vehicle. OBC is a device for power conversion and supply, and it needs to equip with overall and comprehensive protection mechanism for application’s user safety. Therefore, OBC requires protective components to provide over-current protection, over-voltage protection, and over-temperature protection to ensure its normal operation.
With more than 40 years experience in protective component industry, THINKING owns advanced manufacturing process, material development, and overall verification. Its profound experience and advanced technology enable it to offer comprehensive service and reliable protective components to assist customers in overall protection design for OBC.
