600 V IGBT IPM: BM6337x SeriesSimultaneously Achieve Industry-Leading Low Noise and Low Losses for Inverters Used in Home Appliances, Small Industrial Equipment –Specifications–
2023.05.24
The BM6337x series are new 600 V IGBT IPMs (Intelligent Power Modules) that simultaneously achieve industry-leading figures for low noise and low loss characteristics. Two packages are offered for each of four device types with different current ratings, for a lineup of eight new models.
The BM6337x series have been newly developed for power conversion in various inverters such as 3-phase AC 240 V AC servos for use in major household appliances such as air conditioners and washing machines, as well as for applications in smaller industrial equipment such as small-capacity motors for industrial robots.
The BM6337x series were developed in the midst of demands for energy conservation and expectations being placed on the appearance of power devices and modules such as IGBTs for power conversion with reduced power consumption, and with IGBT IPM development prioritizing low losses; as a result, however, noise characteristics are often worse, and so improvement of noise characteristics has also been sought.
BM6337x Series Main Specifications
The BM6337x series are IMPs that integrate gate drivers, bootstrap diodes, IGBTs, and fast recovery diodes for regeneration in a single package.
＜Summary of Specifications and Block Diagram＞
- ・DC input, 3-phase AC output IGBT inverters
- ・Ratings: VCES ＝ 600 V, IC = ±10 A/±15 A/±20 A/±30 A
- ・Low-side IGBT open emitter
- ・Internal bootstrap diodes
- ・High-side IGBT gate driver (HVIC):
SOI （Silicon On Insulator） process used
Driving circuit, High-voltage level-shift circuit
Bootstrap diode current-limiting circuit
Control power supply under-voltage-locked-out (UVLO) circuit - ・Low-side IGBT gate driver（LVIC）:
Driving circuit, Short-circuit current protection circuit (SCP)
Control power supply under-voltage-locked-out (UVLO) circuit
Thermal shutdown circuit (TSD)
Analog temperature output circuit (VOT) - ・Devices for each current rating provided in two packages, HSDIP25 and HSDIP25VC
- ・Error output: Low-side IGBT short-circuit current protection, UVLO, or thermal shutdown activated
- ・Input interface: Supports 3.3 V, 5 V
- ・UL certified: UL1557 File E468261
The high-side IGBTs are driven by a high-voltage level shift circuit consisting of a high-side gate driver (HVIC) and bootstrap diodes. Because bootstrap diodes and a bootstrap diode current limiting function are incorporated, bootstrap diodes and current limiting resistors are unnecessary. An under-voltage-locked-out circuit (UVLO) is provided for floating control power supply.
The low-side IGBTs are driven by an LVIC. A short-circuit current protection circuit (SCP), control power supply under-voltage-locked-out circuit (UVLO), and thermal shutdown circuit (TSD) are provided, and the alarm output (FO) reports an error when a protection circuit is activated. The temperature of the LVIC is detected, converted into an analog voltage, and output (VOT).
Application Examples of BM6337x Series
The BM6337x series have been developed for inverters used with motors in home appliances and industrial equipment. Below are examples of applications and a basic application circuit example.
- ・Inverter devices for AC 100 to 240 Vrms (DC 400 V or lower) motor control
- ・Inverters for air conditioners, washing machines, refrigerators, and other major home appliances
- ・Inverters for smaller industrial equipment such as small-capacity motors used in industrial robots
- ・Other compressor or motor-equipped applications in which inverter control is required
