A Direct Digital Synthesis (DDS) is a type of DC-DC Converter that is used for creating a direct, digital output waveform from an analog input signal. DDS offers an excellent dynamic range and a wide range of output frequency options. It is normally used for creating digital pulse waveform and can be found in applications like communication, automotive, medical and industrial use. The following will discuss the application fields and working principle of DSP-10, DSP-11 and DSP-12.

Application Fields:

DSP-10, DSP-11 and DSP-12 are typically used in isolated power supplies and inductive/capacitive loads. The device is designed to accurately measure and control the output voltage and current in the output power circuit. It is commonly found in applications such as power amplifiers, motor driver circuits, industrial machines, stepping motors, and AC/DC converters. The output power is precisely controlled over a wide dynamic range, making them ideal for AC/DC conversion.

Working Principle:

The working principle of these pulsed DC-DC converters can be explained by the power converter’s control block diagram. It consists of an input controller, an inverter and a modulator. The input controller receives a signal from a switch that specifies the desired output voltage or current. The signal is then transmitted to the inverter which then converts the signal into a high-frequency pulse-width modulated (PWM) waveform. The modulator then modulates the PWM signal in order to achieve the desired output voltage or current. This is done by adjusting the duty cycle of the PWM signal. The output of the modulator is then connected to the power circuit, which then powers the load.

In order to control the output power accurately, the device uses feedback loops and precise digital signal processing techniques. By using a feedback loop, the output of the power circuit is constantly monitored. When a variation is detected in the output, the signal is sent to the input controller which then adjusts the PWM signal accordingly. In addition, the device also makes use of complex digital signal processing algorithms to ensure an efficient working of the converter.

In summary, DSP-10, DSP-11 and DSP-12 are DC-DC converters which are commonly used for power control. They can be used to control the output voltage and current of a power circuit over a wide dynamic range. The device employs a combination of feedback control loops and advanced digital signal processing algorithms to ensure a high level of accuracy and efficiency. Thus, they can be found in various applications like communication, automotive, medical and industrial use.
