Abstract :
Familiar special microprocessor with PWM pulse generator cannot provide enough PWM pulses for multi-modular converters or multilevel converters. Field programmable gate array (FPGA) is applied to implement the multichannel PWM pulse generator with no synchronization and communication trouble due to the single chip structure of FPGA compared with the multi-microprocessor scheme. A three-phase voltage source 5-level cascade inverter prototype with sample time staggered space vector modulation is accomplished to verify the correctness of the proposed multichannel PWM pulse generator
