The parameters of miniature MA-level helical explosively-driven magnetic flux compression generator(HEMCG) are calculated by method of equivalent circuit，and the result indicates that the main loss of HEMCG is non-Ohmic loss．The entire outer diameter of HEMCG with initial inductance of 128.7 μH is about 140 mm，and the length is less than 550 mm．When the initial current injected is 3.6 kA in the experiment, a pulse current with 75.2 μs risetime and 1.87 MA peak value is obtained on the 100 nH load while the seed current is amplified by 519.4 times，which means that the energy amplification coefficient is 209.6，and the conversion efficiency from chemical energy of explosive to electromagnetic energy is 6%．The HEMCG is modulated by cable transformer with about 440 nH primary inductanc
