The influence of the conducting inductance in the auxiliary resonant commutated pole inverter

Abstract

The Auxiliary Resonant Commutated Pole (ARCP) Inverter is well-known by its small EM1 and switching loss. However, in the high v o l t a g e -high power application, there exist some problems such as the difficulty of the complete ZVS realization, influence of the conducting inductance and so forth. In this paper, the characteristics of the ARCP inverter is analysed, with consideration of the conducting inductance influence. The useful analytical results a r e obtained and confirmed by the e x p e r i m e n t .

Energy conversion unit with optimized waveform generation

“…However, one of the main drawbacks of this topology is triggering of the auxiliary switches. This requires additional measuring and timing which reduces the overall system reliability [74,75]. In addition, the extra measurements protect the auxiliary switches against over voltage cause circuit complexity [71].…”

Control simplification and stress reduction in a modified PWM zero voltage switching pole inverter

“…Without the boost stage, the pole voltage may not be able to arrive at the rail level during the resonance in practice and zero voltage switching may be lost [5] [6]. Note that freewheeling diode reverse recovery current and DC bus inductivity can in theory contribute to boost the resonance [3] [9]. However, they can not be counted on as both are second order circuit parameters.…”

A novel firing control and overcurrent protection of the main power switches in the ARCP three phase inverter

“…In order to meet these technical requirements, the ARCP three phase pwm inverter [I], [2] using the SI thyristors as main power switches has been researched and developed [3]- [5].…”
