AC/DC converters are widely used in various power supply applications ranging from light weight power supplies to industrial and medical grade units. The AC/DC converter type PBO-1-S12 is a step-down converter that is used to convert AC power to DC using a single-stage buck topology. It offers excellent power efficiency and is suitable for high-efficiency applications in which highly regulated output voltage is required.

The PBO-1-S12 features an input voltage range of 90 V to 450 V and an output voltage range of 5 V to 120 V. The maximum output current of this converter is 12 A, and the efficiency range is between 85% and 95%. The converter also has a wide temperature range of -55 °C to +105 °C, making it ideal for applications in extreme temperature conditions.

The key features of the PBO-1-S12 include a soft start feature, a pre-bias startup capability, a wide input voltage range, an adjustable operating frequency, fast transient response, and a low output ripple. In addition, it has an over-voltage protection (OVP) feature to protect the load from excessive voltage levels in the event of an over-voltage condition.

The working principles of the PBO-1-S12 converter are based on the concept of power conversion from AC to DC. The input voltage is rectified by a rectifying circuit resulting in a rectified waveform with a peak voltage determined by the input voltage. The rectified waveform is then filtered to produce a DC voltage. This DC voltage is used as the reference voltage, and the output voltage is regulated by controlling the duty cycle of the switching circuit.

The duty cycle of the switching circuit is controlled using a control circuit, which includes a PWM comparator and a feedback loop. The feedback loop senses the change in the output voltage and adjusts the duty cycle of the switching circuit accordingly. The PWM comparator compares the desired voltage level with the reference voltage to determine the appropriate duty cycle for the switching circuit. The feedback loop ensures that the output voltage is accurately regulated even when the input voltage and load conditions vary.

The PBO-1-S12 is a high-efficiency step-down converter that can be used in a variety of applications. It is designed to provide constant current during heavy load conditions and can be used in applications such as lighting, industrial control systems, motor control systems, and battery charging. This converter offers excellent power efficiency and a wide operating temperature range, making it ideal for high-efficiency applications.
