IPW60R080P7優(yōu)勢:

• Ease of use and fast design-in through low ringing tendency and usage across PFC and PWM stages
• Simplified thermal management due to low switching and conduction losses
• Increased power density solutions enabled by using products with smaller footprint and higher manufacturing quality due to >2 kV ESD protection
• Suitable for a wide variety of applications and power ranges

IPW60R080P7潛在應(yīng)用:

This document presents design considerations and results from testing a 2 kW industrial battery charger that is capable of charging 48 V based lead-acid and Li-ion batteries. The design is based on a dual-boost PFC and a half-bridge LLC DC-DC power supply solution, with natural convection cooling, using:

? 600 V CoolMOS™ P7 superjunction (SJ) MOSFETs for hard-switching and soft-switching topologies
? IDH16G65C6 CoolSiC™ Schottky diode 650 V G6 for an attractive price-performance ratio
? BSC030N08NS5 OptiMOS™ 5 80 V power MOSFET for reverse polarity protection
? IDB15E60 600 V silicon power diode
? ICE3PCS01G PFC controller IC for active Continuous Conduction Mode (CCM) power
? ICE2HS01G resonant mode controller
? ICE5QR2280AZ CoolSET™ QR Flyback controller
? 2EDN7524F EiceDRIVER™ 2EDN family of non-isolated dual gate drivers
? IRS21814 600 V high- and low-side gate driver IC
? XMC1403-Q064X0200 AA 32-bit XMC1000 industrial microcontroller

This application note provides a detailed description of the main features and operation under both steady-state and abnormal operating conditions of a 2 kW highly efficient natural convection-cooled industrial battery charger for 48 V lead-acid and Li-ion batteries. This demo board solidly confirms how different Infineon Technologies devices, ranging from power semiconductors to the controllers for the internal converters as well as for the accurate charging profile, perfectly fit a range of industrial applications.

工業(yè)電池48V充電器參考設(shè)計(jì)主要特性:

? Different battery types (chemistries) can be charged, as explained in section 3.1.
? Different battery charging capacities can be selected, as indicated in Table 4.
? Clear signalization of the operation status of the charger during normal operation, as described in section 3.3, and when an error is present, as described in section 3.4.
? Accurate charging profile according to the chemistry type selected as well as the measured temperature of the battery during the charging process, as described in the “Lead-acid and Li-ion charging profiles” section.
? In case larger batteries need to be charged or faster charge capability is needed, the battery charger can be connected in parallel with another unit to achieve this. This operation is clearly explained in section 5.
? High Power Factor (PF) and low Total Harmonic Distortion (THD) response at high-line, as shown in Figure 23.
? Efficiency higher than 92 percent from 20 percent of the rated load (2 kW) upward when Vin = 230 V AC, and efficiency higher than 91 percent of the rated load (1 kW) upward when Vin = 90 V AC, during CCM.
? High performance achieved by using Infineon Technologies best-in-class devices:
− TO-247 600 V CoolMOSTM P7 SJ MOSFETs for both dual-boost bridgeless PFC and half-bridge LLC topologies, along with single TO-220 650 V CoolSICTM sixth-generation Schottky diodes.
− EiceDRIVERTM 2EDN non-isolated gate driver as well as 600 V high- and low-side driver ICs.
− QR Flyback controller ICE5QR4780AZ CoolSET™.
− Super SO8 OptiMOS™ MOSFETs for battery management system control.
? Robust and realiable operation under different abnormal conditions:
− Power Line Disturbance (PLD) events, like AC-Line Drop-Out (ACLDO) and voltage sag, as shown from Figure 30 to Figure 33.
− Surge events that do not represent a serious threat to the integrity of the industrial battery charger according to what it is specified in the Surge immunity (EN61000-4-5)Surge immunity (EN61000-4-5) test in section 8.6.
? In case higher battery voltages are required, section 6 provides a list of changes that would be necessary to make at hardware level. Two different battery voltage ratings are considered: a) 72 V (range 67.2 V to 86.4 V at 30 A max.) and b) 144 V (range 134.4 V to 172.8 V at 15 A max.).

The 2 kW industrial battery charger offers a charging solution that operates on any single-phase 90 V AC to 265 V AC grid worldwide with a 94.7 percent peak efficiency. The charger has two charging profiles implemented: one for Li-ion batteries and the other for lead-acid batteries. The respective charging profiles correspond to the latest trends of battery charging. With the selectable nominal battery capacity (Cnom) feature, the charging current can be automatically adjusted in order to charge different battery sizes and amp-hour ranges to help customers achieve battery charging flexibility.

The charger is designed based on a dual-boost PFC that provides high PF of greater than 0.9 and meets PFC regulation as per IEC61000-3-2 Class A, followed by a converter stage realized by a half-bridge LLC configuration. Infineon’s latest 600 V CoolMOS™ P7 SJ MOSFET enables the design with natural convection cooling. The design has a battery management control system capable of charging both 48 V lead-acid and Li-ion batteries in the different charging modes – constant voltage and CCM.

The battery management control system implemented is designed to optimally charge lead-acid (WET, GEL, AGM, EFB and VRLA) as well as Li-ion (LiPo, Li2MnO3, Li2Mn2O4, Li4Ti5O12 and LiFePO4) batteries used on electric vehicles including E-scooters, E-bikes and low-speed vehicles. Furthermore, an RS485 bus communication protocol feature allows for a master/slave operation that can extract 4 kW max. charging power when connecting two chargers in parallel configuration, ensuring seamless power distribution and a fast charging feature for Li-ion batteries.
