Function Description:
System composition: Adopt STC15F2K60S2 single-chip microcomputer to generate three-way SPWM to drive IR2104 driver IC, and then drive the three-phase H-bridge circuit. Through the latter stage LC filter circuit, the three-phase inverter voltage can be obtained.
Hardware composition: STC15F2k60S2 single-chip microcomputer + IR2104 + three-way H bridge + LCD1602 liquid crystal + buttons;
Inverter principle: Single-chip SPWM drive H-bridge + post-filter;
Adjustment mode: frequency plus key, frequency minus key, amplitude plus key, amplitude minus key;
Frequency adjustment range: 10hz, 20hz, 30hz, 40hz, 50hz, 100hz, 200hz, 300hz, 400hz, 500hz
Amplitude adjustment range: 1/10, 2/10, 3/10, 4/10, 5/10, 6/10, 7/10, 8/10, 9/10 10/10;
Maximum output current: 2A;
Input voltage range: DC (direct current) 12V-40V;
