Operating Principle of MAC-IGBT Small Power Supply
MAC-IGBT power supply adopts the pulse width modulation (PWM) technology, and uses Infineon fourth generation IGBT power module as a switching component, and the filtration module, the rectifier module, the inverter module, the power converter module and the control unit form a whole perfect system. The complete machine has the prominent characteristics of small volume, light weight, high efficiency and energy saving, high reliability, etc.
■ The operating principle is as follows:
■ AC input - rectifier - filter circuit - IGBT power unit;
■ IGBT inverts the above direct current into 20kHz square wave alternating current under PWM waveform control generated by the control circuit;
■ The high-frequency transformer insulates and reduces voltage to transfer power;
■ The output rectifier, the reactor filter and the output conform to the required DC voltage and current;
■ The display circuit displays the operating current and the operating voltage.
