Rectifier power supply

Product overview Periodic commutation (bipolar) lead pole rectifier power supply is a special DC power supply equipment that can automatically or manually change the polarity of the output DC during work. Its core function is to automatically switch the positive and negative polarity of the output terminal according to a preset time period or control instruction, so that the load (such as the workpiece in the plating tank) is alternately in the anode and cathode state. The power supply is mainly for those in the electroplating industry that have special requirements for coating density, adhesion and uniformity. In the process of periodic reversing chromium plating, electrolytic degreasing, alkali copper rolling plating, de-plating, etc., the periodic alternation of positive and negative polarity can be effectively changed.

Product Overview IGBT high-frequency switching power supply is a new generation of DC power supply equipment based on high-frequency PWM pulse width modulation technology, using insulated gate bipolar transistor (IGBT) as the core power device. The basic working principle is as follows: three-phase alternating current is converted into smooth direct current after rectification and filtering, and then converted into high-frequency alternating current (usually 10kHz to 50kHz) by IGBT full-bridge inverter circuit. After step-up or step-down isolation by high-frequency transformer, the final rectifier filter outputs stable DC voltage or current. Compared with the traditional SCR phase-controlled power supply, IGBT high-frequency switching power supply will work from the frequency

Product Overview: A thyristor rectifier power supply is a DC power supply device that uses thyristors (silicon-controlled rectifiers) as its primary power semiconductor. Its fundamental principle is to regulate the output DC voltage and current by controlling the firing angle of the thyristors, thereby converting three-phase or single-phase AC power into continuously adjustable DC power. Silicon-controlled rectifier (SCR) power supplies, with their robust output power capability, occupy an irreplaceable position in the high-power industrial DC power supply field, a role that neither linear nor switching power supplies can fulfill. Product Features: The thyristor power supply offers significant advantages in power scalability, with a single unit capable of delivering several thousand kilowatts, making it ideal for applications requiring low voltage and high current.
