The drive consists of three independent components:<\/p>\n<ul>\n<li>Multi-pulse phase-shifting transformer<\/li>\n<li>Modular, power-cell-based multi-level inverter<\/li>\n<li>Multi-pulse diode-based rectifier<\/li>\n<\/ul>\n<p>This design makes a common bank of capacitors for energy storage and filtering unnecessary, eliminating the need for multiple rectifier-capacitor combinations in individual inverter power modules. DC power is fed to the M2L inverter from a standard transformer \u2014 which can be located remotely from the inverter \u2014 via bridge rectifiers. Power is provided to the DC link as a whole via the DC voltage terminals, not individually fed to each module. Link energy storage is distributed among identical power modules that comprise the M2L inverter rather than relying on capacitors for energy storage. This arrangement greatly reduces arc flash potential and substantially improves reliability. Utilizing a standard transformer and rectifier minimizes the component count as well as the number of cable connections required.<\/p>\n<h3>Customer Benefits<\/h3>\n<\/div><\/section><br \/>\n<div  style='height:1px; margin-top:-24px'  class='hr hr-invisible   avia-builder-el-7  el_after_av_textblock  el_before_av_table '><span class='hr-inner ' ><span class='hr-inner-style'><\/span><\/span><\/div><br \/>\n<div  class='avia-table main_color avia-pricing-table-container  avia_pricing_default   avia-builder-el-8  el_after_av_hr  el_before_av_hr  avia-table-1'  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/Table\" ><div class='pricing-table-wrap'><ul class='pricing-table '><li class='avia-heading-row'><div class='first-table-item'>Benshaw<\/div><span class='pricing-extra'><\/span><\/li><li class=''><strong>Standard multi-pulse isolation transformer<\/strong><br \/>\nLimited number of secondary cables<\/li><li class=''><strong>Standard multi-pulse rectifier<\/strong><br \/>\nLower component count<\/li><li class=''><strong>Distributed DC link energy storage<\/strong><br \/>\nLow energy density<\/li><li class=''><strong>Film capacitors<\/strong><br \/>\nProven reliable<\/li><li class=''><strong>Modular power cell based inverter<\/strong><br \/>\nIsolated faults<\/li><li class=''><strong>Reliable LV (1700V) IGBTs<\/strong><br \/>\nTypical failure in time rate of 100*<\/li><\/ul><\/div><div class='pricing-table-wrap'><ul class='pricing-table '><li class='avia-heading-row'><div class='first-table-item'>Other Solutions on the Market<\/div><span class='pricing-extra'><\/span><\/li><li class=''><strong>Complex integrated multi-winding transformer<\/strong><br \/>\nNumerous secondary cables<\/li><li class=''><strong>Complex power cell integrated rectifiers<\/strong><br \/>\nUnnecessarily high component count<\/li><li class=''><strong>Concentrated energy storage<\/strong><br \/>\nHigh energy density<\/li><li class=''><strong>Electrolytic capacitors<\/strong><br \/>\nProven unreliable<\/li><li class=''><strong>Non-modular integrated inverter<\/strong><br \/>\nCascading failures<\/li><li class=''><strong>Less reliable HV (6500V) IGBTs<\/strong><br \/>\nTypical failure in time rate of 4001<\/li><\/ul><\/div><\/div><br \/>\n<div  style='height:1px; margin-top:-32px'  class='hr hr-invisible   avia-builder-el-9  el_after_av_table  el_before_av_textblock '><span class='hr-inner ' ><span class='hr-inner-style'><\/span><\/span><\/div><br \/>\n<section class=\"av_textblock_section \"  itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/CreativeWork\" ><div class='avia_textblock  '   itemprop=\"text\" ><p><small>* Failure in time (FIT) rate of a device is the number of failures that can be expected in one billion device-hours of operation.<\/small><\/p>\n<h3>Serviceability<\/h3>\n<p>Simple and fast maintenance is ensured through front access only design and advanced diagnostic tools such as Benshaw Connect and the GMC\u00ae remote monitoring system.
