Technical Specifications of 50A 1000V Automatic Cyclic Reversal Rectifier

Structure

The water treatment power supply primarily consists of a rectifier-filter circuit, a full-bridge converter circuit, a high-frequency transformer, a high-frequency rectifier-filter circuit, an auxiliary power circuit, and a main control unit. The main control unit circuit mainly comprises phase loss protection, temperature protection, overload protection, short-circuit protection, and a PWM circuit with PI regulation.

The three-phase grid voltage is rectified and filtered after passing through the power switch, yielding a smoothed 520VDC supply for the inverter circuit. The inverter circuit primarily employs high-power MOSFET or IGBT modules to form a full-bridge converter. When the PWM output control signal drives the power modules through isolated drivers, two sets of diagonal transistors conduct alternately. This generates a high-frequency pulse voltage in the primary winding of the high-frequency transformer. The secondary voltage is transformed by the high-frequency transformer, rectified, and then supplies energy to the load.

Features of Using Our Electrocatalytic Oxidation Power Supply

1. The power supply can operate in either voltage-regulated current-limited mode or current-regulated voltage-limited mode, with seamless switching between the two states.
2. DC output voltage regulation accuracy ranges from 50% to 100%. When input voltage fluctuates by 10% or load changes occur, the output voltage remains stable with regulation accuracy ≤0.5%.
3. Incorporates filtering functionality to prevent interference with instruments during power-up, eliminate grid pollution, and mitigate current inrush phenomena.
4. Phase Loss Protection: Automatically locks out when any phase is missing from the three-phase AC input. Resumes operation automatically after fault resolution.
5. Overcurrent Protection: Automatically enters overcurrent shutdown and alarm state when current exceeds rated value.
6. Short-circuit protection: In case of load short-circuit or internal component short-circuit, the circuit breaker automatically disconnects the power supply.
7. Over-temperature protection: When abnormal temperatures of semiconductor components (e.g., IGBT, Schottky diodes) reach ≥80°C, the electronic switch on the main control board activates, locking the power supply to effectively protect the unit.
