Wiring method of power transformer

Power transformers are not recommended to be connected directly in parallel, it is best to separate the rectifier after connection.

First, the common wiring method of the power transformer: generally use full bridge rectification or full wave rectification.

Second, the single-phase transformer parallel connection method

1. Parallel power supply mode: This method is suitable for resonant circuits.

2. Multiple power supply mode: This method is suitable for starting the load, providing a larger current, so that the motor starts more smoothly.

3. Reverse belt power supply mode: This method is suitable for applications where the motor may sometimes reverse.

Third, single-phase transformer series wiring method

1. Total series power supply mode: This method is suitable for relatively large loads.

2. Partial series power supply mode: This method is suitable for loads requiring less than 10% waveform distortion.
