AC DC converters are electrical devices that convert Alternating Current (AC) to Direct Current (DC). The HWS1800T-15 is a high-efficiency, full-bridge AC DC converter designed for automotive applications. With a switching frequency up to 100 kHz and a high-efficiency of up to 95%, this converter is suitable for applications such as car navigation systems, car radios, car audio systems, and vehicle video systems.

The HWS1800T-15 is based on an alternating current (AC) to direct current (DC) full-bridge converter. It operates in a fixed-frequency, three-phase, PWM (Pulse Width Modulation) mode. Its output is controlled by digital signals, such as the on/off signals from the audio system, car radio, car navigation system, etc.

The HWS1800T-15 operates by converting the AC power into a high voltage DC. This DC is then filtered by a capacitor to reduce the voltage ripple. A pre-regulator is used to keep the output steady and the power factor constant. This pre-regulator also reduces stress on the components. Then, a bridge rectifier is used to change the DC signal into a suitable direct current (DC) for the application.

The HSW1800T-15 also features overvoltage protection (OVP) for protection against voltage spikes and overvoltages. This protection can be set to protect the converter against over voltage conditions. It also contains thermal shutdown (TSD) which prevents damage and overheating of the converter when the temperature is too high.

The HWS1800T-15 also includes a low-noise switching frequency (LFS) circuit that keeps the switching frequency steady and stable. The advantage of the LFS mode is that it reduces the EMI interference from the converter, allowing it to operate in noisy environments such as those in automotive applications.

The HWS1800T-15 is a high-efficiency, full-bridge converter suitable for automotive applications. It operates in a fixed-frequency, three-phase, PWM mode and its output is controlled by digital signals. It has an input power range from 1-75V and an output power range from 1-16A. Its high efficiency and low-noise switching frequency make it suitable for automotive audio and navigation applications.
