Abstract
The invention provides a three-energy-storage-capacitor dual-output Z source half-bridge converter which comprises a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a fifth capacitor, a first inductor, a second inductor, a first switch tube, a second switch tube, a third switch tube and a diode. A first conventional half-bridge converter body is formed by the first capacitor, the second capacitor, the first switch tube and the second switch tube, a second conventional half-bridge converter body is formed by the second capacitor, the third capacitor, the second switch tube and the third switch tube, and a Z source impedance device is formed by the fourth capacitor, the fifth capacitor, the first inductor and the second inductor. The diode is used for preventing an electric current of the Z source impedance device from flowing back to a power source. According to the three-energy-storage-capacitor dual-output Z source half-bridge converter, dual-channel output is achieved only through the three switch tubes, the reliability is high, the output voltage range is wide, output alternating current pulse waveforms are abundant, and the three-energy-storage-capacitor dual-output Z source half-bridge converter is particularly suitable for dual-output occasions such as electrochemical power supply devices including electrolysis power supply devices, electroplating power supply devices and the like, and multi-output-required green energy occasions such as distributed power generation.
Description
Technical field [0001] The invention relates to the technical field of power electronic converters, in particular to a three-energy storage capacitor and dual-output Z-source half-bridge converter. Background technique [0002] In a conventional half-bridge converter, the inverter bridge arm is directly connected in parallel with the DC voltage source. When the upper and lower switch tubes of the inverter bridge arm are turned on due to false triggering, a very large current will flow and the switch tubes will be damaged. Moreover, the amplitude of the output AC voltage of this type of half-bridge inverter is only half of the input voltage, which is a step-down inverter with a relatively narrow output voltage range. In order to increase the amplitude of the output AC voltage, the traditional method is to add a boost link in the front stage of the inverter, or connect a transformer at the output end to boost the voltage. At least one more switch tube needs to be used in the schem...
