The invention discloses a high-efficiency current amplification circuit based on H-bridge structural design, the current amplification circuit comprises a power supply module, two control modules, an H-bridge amplification module, a
logic control module, a protection module and a load module, the power supply module is used for providing a
direct current input
voltage, each control module comprises a half-bridge controller, two resistors and two capacitors, and the
logic control module is connected with the H-bridge amplification module. Pins of each half-bridge controller are set to be a VCC end, an IN end, an SD end, a COM end, a VB end, an HO end, a VS end and an LO end, and the two resistors are used for
limiting current and adjusting
voltage. The H-bridge structure is cooperated with the IRF540N MOS tube,
high voltage, large current output, multiple protection and redundancy design are realized, long-term stable operation in an industrial environment is ensured, general elements and a
modular architecture are adopted, the purchase and maintenance cost is reduced, and by adjusting the
capacitance value of a
capacitor, the resistance value of a
resistor or the model of the MOS tube, the device can be expanded to scenes with
higher power or different voltages.
