Radar and Communication Field
In radar systems, pulse transformer cores are used in pulse modulators and signal coupling links between transmitters and receivers. They can accurately transmit high-frequency, narrow pulse signals, ensuring the accuracy of radar in target detection and positioning.
In communication equipment (such as microwave communication and digital communication devices), they can achieve signal isolation and matching between different circuit modules, reduce signal interference, ensure the integrity of pulse signals during transmission, and improve communication quality.
Power Electronics and Energy Field
In power electronic switching circuits (such as thyristor and IGBT drive circuits), pulse transformer cores are used to transmit trigger pulse signals, realizing electrical isolation between control circuits and power circuits, ensuring safe and stable operation of the circuits, and improving the transmission efficiency of trigger signals.
In new energy power generation systems (such as the inverter control part of photovoltaic power generation and wind power generation), they can be used to isolate high-voltage and low-voltage circuits, transmit control pulses, and ensure accurate signal interaction during energy conversion.
Medical Device Field
In medical equipment (such as CT scanners, nuclear magnetic resonance equipment, and high-frequency electrosurgical units), pulse transformer cores are used for isolation and transmission of pulse signals. For example, in high-frequency electrosurgical units, they can safely transmit low-voltage pulse signals from the control circuit to the high-voltage output end, while achieving electrical isolation between the patient/operator end and the equipment end, ensuring the safety of patients and operators.
Industrial Control and Measurement Field
In industrial automation control systems, pulse transformer cores are used for signal transmission in PLCs (Programmable Logic Controllers) and servo drive systems. They realize isolation and matching of control pulses, avoid interference from strong current circuits to weak current control circuits, and improve system stability.
In precision measuring instruments (such as oscilloscopes and pulse signal generators), they can be used for signal attenuation and impedance conversion, ensuring accurate transmission of pulse signals in the measurement process and improving measurement precision.
