Working Principle

The APT40DQ120BCTG is an advanced rectifier array that uses four SCR (silicon controlled rectifiers) to provide two-phase rectification. It is designed to provide low on-state voltage, low forward voltage drop and fast switching. The four SCR are arranged in two sets, each set containing two SCR. Each set is normally connected in series with the other, providing balanced current flow during rectification. This device also utilizes a forward-biased diode configuration, in which a crystal rectifier is connected in parallel with each of the four SCRs. The forward-biased diode lowers the forward voltage drop of the rectifier array, allowing it to produce higher power efficiency.

The two-phase rectification process of the APT40DQ120BCTG is enabled using the four SCRs, with each SCR switching the current flow from the positive to the negative phase. When there is enough voltage on the gate of one SCR, it will become conductive, causing a current to flow through it. As the current flows, it generates a voltage on the anode of the other SCR, which causes that SCR to also become conductive. As a result, current may flow through both SCRs, and the polarity of the voltage will be reversed. This process then repeats itself, alternating the polarity of the voltage and enabling rectification.

The APT40DQ120BCTG is an advanced rectifier array that can provide reliable operation and improved power efficiency. It is best suited for high-reliability applications and is designed to withstand high levels of shock and vibration. As a result, it is a popular choice for applications that require reliable operation and high power efficiency.
