The PD432206 module is a two-phase switch mode rectifier module that controls direct current (DC) power input from a three-phase, AC power source. It is composed of high efficiency and low cost insulated gate bipolar transistors (IGBTs) and rectifier diodes. It can control both bipolar and unipolar power waves with switching frequency up to 16kHz. Unipolar power waves are switched at zero crossing points, while bipolar power waves are switched at a certain angle between zero and peak value. The module also has built-in soft-start, output current and voltage regulation, and overtemperature protection.

The PD432206 module has a wide range of application fields, such as telecommunication and power electronics. In telecommunication applications, it is used to switch current to control direct current input from a three-phase AC power source, which can be used in switches, amplifiers, and power converters. It is also used in uninterruptible power supplies, motor drives, power conditioners, power converters, and inverters. The module also works for load balancing for inverter applications.

The PD432206 module applies the principle of voltage control, which means that the voltage is set in the IGBTs, controlling the instantaneous current and voltage. The Working principle of the module can be divided into series-resonant and parallel-resonant. In series-resonant, a series resonant circut is established between the rectifier diodes and the IGBTs. When a certain voltage is applied to the bridge, the voltage will build up in the IGBTs and inductance-capacitance resonance will occur. This generates an oscillating current that can be switched with a steady-state current. In parallel-resonant, a parallel resonant circut is established between the diodes and the IGBTs. The parallel resonant circuit is able to operate smoothly with constant frequency and gain stability in current. The oscillating current generated by the resonant circuit is then switched with a steady-state current. The PD432206 can either operate in series-resonant or parallel-resonant mode.

In conclusion, the PD432206 module is a two-phase switch mode rectifier module which has a wide application field, such as telecommunication and power electronics. It can control both bipolar and unipolar power waves with switching frequency up to 16kHz and has built-in features like soft-start, output current and voltage regulation, and overtemperature protection. It applies the principle of voltage control, and its working principle can be divided into series-resonant and parallel-resonant.
