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.

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.

Small-signal model and design of the active-clamp forward converter with peak-current control mode;

Aimed at the shortcomings of the micro-plasma oxidation technique, a high frequency power micro-plasma oxidation supply based on IGBT and peak-current control mode is designed.
