AC DC converters are commonly found in the modern marketplace. With the potential of high efficiency, low cost, size reduction, and a wide range of performance, AC DC converters are a popular choice. NMP650-HEEE-00 is a type of AC-DC converter that offers these advantages.

The NMP650-HEEE-00 offers a wide range of applications, from producing high voltage levels to driving medical, motor control, and audio power supplies. The converter is a single-phase, high voltage step-down converter with integrated power factor correction, suitable for AC mains inputs with voltages between 85VAC and 250VAC. It provides a fairly constant, regulated, low voltage output with a peak current of 650A.

In terms of working principle, the NMP650-HEEE-00 is a full-bridge, interleaved topology converter. It’s equipped with an integrated pre-driver and integrated high and low-side power MOSFETs, enabling integrated solution and significant overall size reduction compared to a discrete approach. The power conversion process starts by rectifying the AC input voltage to a DC voltage and then converting it in current mode control to a regulated output voltage.

The power stage features a half-bridge inverter that uses two pairs of parallel connected MOSFETs to form a full-bridge phase leg. The current mode control is implemented with an alternating-channel controller with 30KHz switching frequency where two adjacent phases switch alternatively. A feedback loop is also included to modulate the input current and prevent input harmonic distortion.

The NMP650-HEEE-00 is a high voltage, precise, high power, high efficiency, and cost effective AC-DC converter. Its integrated pre-driver, integrated high and low-side MOSFETs, and alternating-channel current control make it a suitable choice for high power applications. With its multiple applications, it’s definitely an excellent choice for the modern market.
