Contimuously adjustable current and voltage, wide adjustment range, high duty cycle, continuous welding.
电流电压边续可调,调节范围宽,负载持续率高,可连续焊接。
In the design of current-mode PWM DC-DC converters, the slope compensation method widely used to prevent sub-harmonic oscillation can significantly weaken the load capacity under a high duty cycle.
电流模pwm集成dc - DC变换器设计中,为了防止亚谐波振荡而普遍采用的斜坡补偿,会在占空比较大时严重影响芯片的带载能力。
Secondly, the low duty cycle leads to the high voltage and current ripple, and enlarges the filter size.
