Along with microwave digital transformation of large-scale development.Intelligent high frequency switch power supply system to replace the traditional silicon rectifier power supply system.High frequency switch power supply the introduction of technology, which makes the power equipment has the ac input voltage range wide, high frequency, small volume, stable and reliable work, convenient maintenance etc.Especially suitable for unattended, centralized control in the digital microwave communication system.High frequency rectifier module as dc system rectifier element, for substation relay protection, communication, remote device and circuit breaker operation and recurrent load provide stable dc power supply, it directly affects the reliability of the safe and stable operation of the transformer substation equipment.

Shanghai Elinker electrical Co,LTD as domestic outstanding terminal manufacturers, its terminal are widely used in high frequency rectifier module,
High frequency rectifier module working principle:

Three-phase ac input by the first lightning processing and EMI filter. This part of the circuit can be effective absorption lightning residual voltage and power grid peak, guarantee the module level after the safety of the circuit.

Three-phase ac the rectifier and passive after PFC into high voltage direct current, the full bridge PWM circuit after conversion for high frequency communication, then through high frequency transformer isolation decompression after high frequency rectifier output.

Module control section responsible for PWM signal generation and control, ensure the stable output, at the same time for each part module for protection, provide "four control" interface.
