Based on the experiment for EDM of carbide material, the influences of electricity parameters, such as pulse width and peak value of current, on the machining performances, including process efficiency, electrode wear and machined surface roughness, are researched, and the effecting mechanism is analyzed.

n this paper, we studied the effect of Bi3+ on peak current ip and peak potential p of the cathodic copper depositon reaction of copper electrorefining when Bi3+ existed in the electrolyte of acidified CuSO4 by cyclic voltammetry method, and determined the reversibility of copper deposition reaction according to the shape of cyclic voltammetry curve.

The concentration of formaldehyde ranges from 10~(-4) to 10~(-5)mol/L, and peak current is linear.

SCE),the peak current is linearly proportional to its concentration in the range from 4.

This paper presents the principles and features of switching power supply in the peak current control.

The aim of this paper is to discuss new solutions in the design of insulated gate bipolar transistor (IGBT) gate drivers with advanced protections such as two-level turn-on to reduce peak current when turning on the device, two-level turn-off to limit over-voltage when the device is turned off, and an active Miller clamp function that acts against cross conduction phenomena.

The peak current mode PWM controller can limit the duty cycle.
