It is also used in crane drives, industrial robots, and HVAC systems. In telecommunications applications, the 43CTQ100 is used for base station power supplies and telecom system power supplies. It is also used in power over Ethernet (PoE) solutions.Working PrincipleThe 43CTQ100 rectifier module is a three-phase power rectifier designed to rectify AC current in 1750 volts and 100 amperes. The device is constructed from low profile, high-efficiency power modules, which results in a compact and reliable package. The device works by using a three-phase bridge rectifier circuit to produce DC power from the AC input. The bridge consists of three diodes for each of the three phases, which enable the rectification process by allowing current to flow in one direction and blocking current in the reverse direction. The bridge is used to transform the AC voltage into a unidirectional voltage, which can be used to power the system. The device works by converting the incoming AC power into DC power in three stages: rectification, filtering, and regulation. Rectification: During this stage, the incoming AC power is converted into low-voltage DC power via the bridge rectifier circuit. This is done by blocking any current flowing in the reverse direction. Filtering: During this stage, any residual AC ripple is filtered out. This is done using capacitors, which absorb the ripple and regulate the output to produce a smoother DC signal. Regulation: During this stage, the DC signal is regulated to the required output voltage and current. This is done using voltage regulators and current regulators.ConclusionThe 43CTQ100 rectifier module is a reliable and efficient diode for power rectification and has superior thermal performance allowing for more efficient operation than traditional rectifiers. It is suitable for a variety of applications, including automotive, industrial, and telecommunications. The device works by using a three-phase bridge rectifier circuit to produce DC power from the AC input and can be configured for four-wire, three-wire, and two-wire conversion. It is designed to protect the system against over-voltage, over-current, short-circuit, over-temperature, and noise.
