Power Electronics Europe Feb/March 2023

PRODUCT UPDATE 23 www.power-mag.com Issue 1 2023 Power Electronics Europe The power supply has a 0.98 power factor and delivers a regulated 360V DC non-isolated voltage from an AC input. The PF1500B-360 can be used to drive isolated high voltage input DC/DC modules in a distributed power architecture configuration, or loads requiring a high voltage DC input. Applications include semiconductor fabrication, LED lighting and custom power supplies using power modules. With an input of 170 to 265V AC, the PF1500B-360 provides 1,512 and 1,008W when operated from 85 to 265V AC. Efficiency of 96.5% efficiency ensures reliable operation with baseplate temperatures of up to 100°C and in ambient temperatures of -40 to 85°C. The industry standard full brick package measures 116.8 x 61 x 12.7mm high for low profile applications. The module provides a 10 to 16V 10mA auxiliary voltage and has a remote on/off and an inverter good signal. An enable function is available to activate isolated DC/DC converters when the output voltage is greater than 360V DC to synchronise output rise times. Parallel connection with current sharing of up to three modules is possible for additional output power. Input and output to baseplate isolation is 2,500V AC. The module is certified to the IEC/EN/CSA/UL 62368-1 standards and is CE / UKCA marked to the low voltage, EMC and RoHS EU Directives and UK regulations. With external circuitry, the module will meet radiated and conducted emissions and comply with the IEC 61000-4 immunity standards. https://product.tdk.com/en/products/power/index.html AC/DC power factor correction module offers up to 1,512W Smart power device manages safe power distribution low loads, says the company, for precise power control system design that can detect even the smallest abnormalities. Other features are built-in charge pump, self-diagnostic feedback by load current sense and load short circuit, overheat detection, sense current output and GND open protection. The single channel, high side IPD has low Ron of of 2.3m Ω at 25°C (typical). The intelligent power device (IPD) addresses E/E architectures as they evolve in automotive design. In a conventional distributed E/E architecture, power supply from the battery is distributed to each electronic control unit (ECU) via long, thick wires from a power box consisting of mechanical relays and fuses. IPDs have a longer life and are maintenance-free compared to mechanical relays, so they can be placed anywhere in the vehicle. As the automotive industry moves toward centralised or zoned E/E architectures, IPDs offer flexible power supply networks using shorter, thinner wires. The RAJ2810024H12HPD supports 3.3/5.0V logic interface and complies with AEC-Q100 and RoHS automotive standards. The RAJ2810024H12HPD is available today in sample quantities with mass production scheduled in Q1 2024. https://www.renesas.com/eu/en/products/automotive- products/automotive-power-devices/automotive-protected-and- intelligent-power-devices The RAJ2810024H12HPD is available in the TO-252-7 package which reduces the mounting area by about 40% compared to the conventional TO- 263 package product. It measures 6.10 x 6.50mm, excluding pins. Intended for use in vehicles equipped with next-generation E/E (electrical/electronic) architectures, it has a current detection function for abnormal currents such as overcurrent and detects abnormal currents even at Miniature isolated single and dual-output high voltage DC/DC converters from Advanced Energy in the AEQ series supply up to 600V DC at 0.5W from 5V DC input. The UltraVolt AEQ series are designed for power conversion in a range of ISM (industrial, scientific, medical), life science and semiconductor equipment applications. They are housed in a 0.5 x 0.5 x 0.5 inch / 127 x 127 x 127mm (cube) solid vacuum encapsulated package and are protected against shock and vibration. Benefits include an output that is proportional to the control pin voltage, giving complete programmability from zero to the maximum rated value. Output stability is within 5% at maximum Vout and full load. A high input-to- output isolation rating of ?1500V DC supports precise output voltage control and meets safety levels required for handheld equipment. They also support compliance in medical and life science applications. The small form factor make them suitable for use in high voltage products where space and weight are critical application requirements. Conor Duffy, vice president of marketing, medical power products at Advanced Energy, says: “The series is particularly well-suited for hand-held and portable devices ranging from silicon detectors and avalanche photo diodes to MEMS devices and ultrasonic transducers. Its programmable control enhances flexibility, precision and reliability to address specific application needs.” The AEQ series comprises unipolar 100 to 600V models and bipolar versions from ?50 to ?300V. Higher power and voltage levels are planned for later releases. All devices have UL/cUL and IEC-62368-1 safety approvals.
