IntroductionDC DC converters are a type of power conversion electronics that is used to transfer electrical power from one DC voltage source to another. The most common use of DC DC converters is to convert a voltage source from one range to another, for example from a 12V source to a 24V source. The RTS-153.3/H-R is a high frequency, half bridge, DC DC converter that is designed to convert a source voltage of 10V-90V DC to a target voltage of 13V to 12V DC.Design of RTS-153.3/H-RThe RTS-153.3/H-R is a high frequency DC DC converter, which is rated to operate at thermal powers up to 135 Watts. The design of the converter makes use of a half-bridge topology, which means that it contains two arms, each containing a single MOSFET that works in sync to control the power transfer from input to output. The RTS-153.3/H-R also has a soft start feature, which allows for a gradual increase in power output, while avoiding large inrush currents.Features of RTS-153.3/H-RThe RTS-153.3/H-R converter offers a wide range of features to satisfy various requirements. These include: a soft start feature, programmable frequency range, automatic voltage control (AVC) with over-voltage shutoff, over-voltage recirculation, transient current limit, and thermal shutdown protection. Additionally, the RTS-153.3/H-R has a high frequency PWM generator, which enables the converter to operate at frequencies up to 160kHz. This high frequency operation is beneficial for achieving high efficiency while reducing the size of the components used in the design.RTS-153.3/H-R Application Field and Working PrincipleThe RTS-153.3/H-R DC DC converter is used in a variety of applications, including industrial, automotive, and medical systems. It is generally used to convert a higher voltage source to a lower voltage, such as 12V to 24V, or 24V to 12V. This makes it suitable for use in a wide range of industrial and automotive applications, as well as in medical electronics such as electrocardiogram (ECG) machines and Ventricular Assist Devices (VADs).The working principle of the RTS-153.3/H-R is based on the design of the half bridge circuit. This circuit is composed of two MOSFETs, which are connected in series. When the MOSFETs are driven by a high frequency PWM signal, they can create an alternating voltage, leading to a constant voltage at the output. The PWM signal is generated from the internal programmable frequency range. The output voltage is controlled by the automatic voltage control (AVC) circuit, which continuously adjusts the frequency of the PWM signal to keep the output voltage within a pre-defined range. In addition, the RTS-153.3/H-R has over-voltage protection, over-voltage recirculation, and a thermal shutdown feature, which all protect against damage to the device and connected components.ConclusionThe RTS-153.3/H-R is a high performance, high frequency DC DC converter that is designed for reliable and efficient power conversion. Its features, such as a wide input voltage range, adjustable output voltage range, and programmable frequency range, make it suitable for a wide variety of applications, including industrial, automotive, and medical systems. Its high frequency operation and high efficiency make it a reliable and cost-effective choice for many applications.
