Three-Phase Power Meter Reference Design

The three-phase power meter reference design is used to measure and record active and reactive energy in directly connected three-phase networks. It is pre-certified to the European EN50470-1, EN50470-3, Class B and Class C, and IEC 62053-21 and IEC 62052-11 international standards for active energy class 2 and class 1 electronic meters.

KV Series Full-Bridge DC-DC Switched Mode Power Supply (SMPS)

The full-bridge DC-DC switch mode power supply reference design is based on V-Series MCUs and is intended to provide examples of power conversion applications. A full-bridge DC-DC converter is a transformer-isolated step-down converter. The full-bridge topology consists of a full-bridge inverter module, transformer, synchronous rectifier module and filter.

Circulation Pump Inverter Reference Design

This reference design introduces PMSM safe motor control software optimized for the dedicated HW HVP-MC3PH-LITE equipped with Kinetis V-series MCUs. The purpose of this reference design is to help customers develop motor control solutions with safety features for controlled heating systems, electric circulation pumps, water installations and other equipment used in industrial applications. The reference design hardware is targeted at circulating pump applications but can be reused in general three-phase motor control applications up to 60 W from 110 V to 230 V AC. The reference design hardware uses NXP's cost-optimized MCU MKV10Z32 with core M0+ and NXP high-voltage DC-DC converter TEA1721. Integrated power modules, surge circuitry, and single-shunt current sensing are also implemented. In the reference design software, sensorless PMSM control with IEC60730/IEC60335 Class B device safety is implemented, including MCU core, memory and peripheral testing, program flow inspection and other safety-related functions. Customers can reuse design reference manuals, schematics, firmware and manufacturing files to accelerate product design.

Motor control design based on LPC860 MCU

This LPC860-based motor control reference design includes PMSM flux direction control and BLDC motor commutation control. LPC860 utilizes flexible timers and ADC modules to provide a complete set of peripherals required for motor control, making it suitable for home appliance applications with three-phase motors or multiple DC brush motors.

The motor control reference design uses the LPCXpresso860-MAX evaluation kit and the FRDM motor control development kit, which includes the FRDM-MC-LVPMSM and FRDM-MC-BLDC driver boards to drive the motor. The controller uses a Flextimer (FTM) to generate a PWM signal and utilizes NXP's RECESL control algorithm library to trigger the ADC in an interrupt to run the motor control algorithm after the ADC sampling is completed.​

Breadboard without jumpers: Based on Raspberry Pi Pico, analog switch matrix replaces jumpers

Flirting with jumper caps is a common practice on most boards, but not this board, which is designed to replace all those wires with an analog switch matrix. All one has to do is plug in the device and make a virtual connection on the accompanying GUI. There are also many built-in functions such as DAC and ADC, and the circuit can be switched under the prototype as needed. It also has some LEDs embedded in the breadboard area that light up and provide visual cues that they are connected to each other.
