125 Vdc Modular Three-Phase Rectifier

NASN 125Vdc three phase input rectifier module is ac-dc converter with high-frequency isolation, features · High reliability and power density.

The 125Vdc three phase rectifier module have 20A and 40A capaicty for your choice. For big power supply system, 125Vdc 40A three phase rectifier module is good choice with compact size and high power density.

The three-phase input power supply is input to the rectification circuit through an EMI filter, which rectifies the AC into pulsating DC output. The pulsating DC is converted into a flat DC power supply through an active power factor correction (PFC) circuit. The DC/AC high-frequency inverter converts the DC into a high-frequency AC power source, and the high-frequency AC is converted into high-frequency pulsating DC through a high-frequency rectification circuit. This DC is then output through high-frequency filtering.

The DC/AC high-frequency conversion circuit adjusts the pulse width of the conversion circuit under the control of the pulse width modulation (PWM) circuit to achieve voltage regulation (including voltage stabilization and voltage setting).

The entire charging module works under the monitoring of the MCU, including module protection, voltage adjustment, etc. At the same time, the MCU reports the operating data of the charging module to the monitoring module and receives control commands from the monitoring module.
