DC–DC converters are electrical circuits which can convert a voltage from one level to another, typically through transforming the voltage to an intermediate level and then rectifying and re-converting to the final voltage. The IHL0224D12 model is an example of a DC DC converter, designed for use in a variety of applications. This article will describe the application fields and working principle of the IHL0224D12 model.
Application
The IHL0224D12 model was designed for use in two primary application fields: as a voltage source converter (VSC) or as a programmable active filter (PAF). For VSC applications, the device can be used as a rectifier, invertor, or as a load controller. Additionally, the IHL0224D12 can be configured to operate as a programmable active filter. In active filter applications, it can be used to modify waveforms, eliminate harmonics, or improve system response.Working Principle
The IHL0224D12 uses direct torque control (DTC) to regulate the load voltage. The DTC approach is based on the control of the torque angle by adjusting the width of the pulses of the PWM signal applied to the switch of the converter. The torque angle is related to the modulation index, expressed as the ratio of the fundamental frequency and the switching frequency of the converter. In order to ensure an optimal performance of the converter, the device uses a hysteresis-based current control loop to stabilize the system at steady-state conditions. In this scheme, the switching power transistor is on until the magnitude of the output current reaches it\'s upper threshold current and off until the output current magnitude reaches it\'s lower threshold current. An integral control loop is utilized to adjust the width of the pulse when the output current is between the upper and lower thresholds.When the converter is used for active filter applications, additional control techniques need to be employed. The most commonly used approach for this application is the phase-domain analysis and synthesis technique. This technique makes use of the information from the reference and sensed voltage waveforms in order to determine the harmonic content of the pulsating load voltage. This information is then used to determine the required switching pattern and the control parameters required to eliminate the harmonics in the pulsating load voltage.Conclusion
The IHL0224D12 is a versatile DC DC converter designed for use in a variety of applications. The device can be used as a voltage source converter or as a programmable active filter. In order to ensure stable operation, the device makes use of the direct torque control approach and a hysteresis-based current control loop. Additionally, when used for active filter applications, the device must be configured using an advanced phase-domain analysis and synthesis technique.The specific data is subject to PDF, and the above content is for reference
