GENERAL DESCRIPTION The Commander 500 is a diesel engine-driven welding power source capable of producing 500 amps at 40VDC at a 100% duty cycle. The engine is coupled to a brush-type alternating current generator . This AC output is rectified and controlled by Chopper T echnology to produce DC current for multi-purpose welding applications. The Co[...]

WELD WINDINGS, RECTIFIER, POWER MODULES AND FEEDBACK The three-phase stator weld windings are connected to a three-phase rectifier bridge. The resultant DC volt- age is applied to four paralleled capacitors incorporat- ed within each of the two power modules. There are two capacitors in each module. These capacitors func- tion as filters and also a[...]

ANALOG CONTROL POWER SUPPL Y BOARD AND WELD CONTROL BOARD The Analog Power Supply PC board, which is powered by 80 VDC derived from the filter capacitors on the Power Modules, supplies various regulated DC volt- ages to operate the Weld Control PC board circuitry . It also supplies two regulated DC voltages to operate the IGBT driver circuitry on t[...]

INSULA TED GA TE BIPOLAR TRANSIST OR (IGBT) OPERA TION An IGBT is a type of transistor . IGBT s are semicon- ductors well suited for high frequency switching and high current applications. Drawing A shows an IGBT in a passive mode. There is no gate signal, zero volts relative to the source, and therefore, no current flow . The drain terminal of the[...]

PULSE WIDTH MODULA TION The term PULSE WIDTH MODULA TION is used to describe how much time is devoted to conduction in the cycle. Changing the pulse width is known as MODU- LA TION. Pulse Width Modulation (PWM) is the varying of the pulse width over the allowed range of a cycle to affect the output of the machine. MINIMUM OUTPUT By controlling the [...]

CHOPPER TECHNOLOGY FUNDAMENT ALS The new era of welding machines such as the Commander 500, employ a technology whereby a DC source is turned on and off (chopped up) at high speed, then smoothed through an inductor to control an arc. Hence the name “ Chopper . ” The biggest advantage of chopper technology is the high-speed control of the arc, s[...]
