The NC75IB2 is an industrial-grade power converter that integrates a battery charger, DC/DC converter and motor controller into a single platform. It is used in a wide variety of applications, from providing reliable power to motors and other equipment in harsh industrial environments, to powering and controlling electrical components in commercial and residential buildings.

The NC75IB2 is a versatile device that can provide efficient and reliable power conversion in various applications. It utilizes a wide DC input voltage range of 9.0 to 75V, and its output can be adjusted up to 80V for high-power motor control applications. The output switches automatically between boost and buck mode as required to maintain a constant output voltage.

The NC75IB2 also features several additional features. It includes an integrated battery charging system, which can be used for both NiCd and Li-Ion batteries. This allows it to be used for a variety of battery packs, including those used for medical, automotive, and portable electronics applications. It also includes a built in Motor Initial Torque (MIT) control and over-voltage protection circuitry, designed to ensure the reliability of the motor start up and smooth operation.

The NC75IB2 is designed to meet a wide range of industrial and commercial power requirements. It is suitable for applications such as motor control, industrial power conversion, safety systems, and more. It can be used for motors up to 10KW in high-power applications, and for smaller-scale motor control and/or power conversion in various places such as motion systems, robotics, and consumer electronics.

The working principle of NC75IB2 is based on the Boost-Buck principle, where a boost converter is used to step up the input voltage and a buck controller to step down the output voltage. These converters perform their respective operations with the help of two MOSFET switches. The MOSFETs are controlled by a dedicated control IC, which in turn is set with PWM switches.

The Boost converter provides a stable output voltage (Vout), which is achieved by coupling two MOSFET switches, one on the input and one on the output. The switches are connected to a voltage trigger circuit, which is set by the control IC via Pulse Width Modulation (PWM). When the input voltage falls below the voltage threshold, the boost converter will switch ON, which will cause the input voltage to increase, thus providing a higher output voltage.

Similarly, the buck converter with its two MOSFET switches is designed to reduce the output voltage. The lower voltage is achieved by providing a control voltage to the MOSFETs via the PWM switches. The output voltage from the Buck is then adjusted according to the setting of the control IC. This allows the output voltage to be regulated according to the requirements of the application.

The NC75IB2 offers enhanced reliability and safety for applications ranging from industrial to commercial. Its built in features such as MIT control, over-voltage protection, and battery charging capability make it the ideal choice for motor control and power conversion in various applications. By combining flexibility, power efficiency, and reliability in one integrated platform, the NC75IB2 provides an effective and cost-effective solution for controlling and powering various motors and equipment.
