The rectifier adopts a high-frequency rectifier circuit, with high inverter frequency, fast control speed and high power factor of the equipment;
The incoming line of the unit is equipped with an EMI filter reactance device, which reduces the interference of the power grid to the power supply and the interference of the power supply to the power grid;
The new switching power supply adopts multiple modules in parallel, with a small single module, low requirements for electronic components and low failure rate;
Liyuan Haina high-power high-frequency switching power supply uses a number of key technologies to solve the problems existing in the previous high-power high-frequency switching power supply, mainly as follows:
* Adopt full-bridge phase-shifted soft switching control mode to eliminate switching stress to the maximum extent;
* Adopt advanced logic interlock control circuit to eliminate pulse false trigger and overcome the short circuit of bridge arm;
* The problem of magnetic bias is well eliminated, which mainly shows the following two aspects: the main transformer uses series DC blocking capacitor primarily; Add an automatic bias correction circuit;
The whole machine adopts multi-unit parallel combination mode, and each unit is controlled by high-speed digital network, which solves the problems of signal attenuation and interference well. Each sub-unit has its own automatic correction and regulation system of current and voltage, so as to achieve the effect of complete current sharing.
Adapt to wind off-grid direct hydrogen production, maximum power point tracking (MPPT), improve energy utilization, microsecond fault protection, fast and reliable protection of equipment and system safety
