UMR11NTR Discrete Semiconductor Products

Introduction

UMR11NTR is a three-phase full bridge rectifier composed of six ultra-fast antiparallel diodes and array technology. The product has greatly improved power density and losses under reverse-recovery current. Moreover, it has improved the stability of transient decomposition recovery and is easy to use.

Application Field

As a particle of diodes and rectifiers array, UMR11NTR can be used in automotive, solar, wind, inverters, UPS, chargers, welding and other fields. It can provide a low power density and low-loss solution, and thus can meet the alternating current (AC) and direct current (DC) conversion demand of various switches, rectifiers and inverters.

Working Principle

Under tri-step control, the UMR11NTR rectifier detects the power grid voltage and automatically adjusts the full bridge rectifier voltage, which can prevent current and voltage outages. Its operation is based on an active bridge circuit. When an AC voltage is applied, the current will form a full-wave rectified output. The rectified voltage can be further smoothed and stabilized by connected capacitors or filter inductance. It can also achieve pulse-width modulation (PWM) in a single-stage circuit and achieve high-efficiency, low-loss operation.

Conclusion

UMR11NTR is a high-efficiency and low-loss rectifier solution. It has good circuit simulation performance and provides a stable and reliable interface for hardware operation. This rectifier has been widely used in automotive, solar, wind, inverters, UPS, chargers, welding, etc. In addition, the application of this rectifier simplifies the process of rectification and smoothing, making it possible to form a single-stage circuit to achieve pulse-width modulation. In summary, UMR11NTR is a good rectifier solution.
