Quality, safety, risk, and compliance management software
Ideagen has launched a new and improved version of its Q-Pulse application to coincide with the 25th anniversary of the software. Q-Pulse
is used across the energy industry to help organizations comply with a variety of quality and risk standards including ISO 9001, 14001, 45001 (OHSAS 18001), ISO/TS 29001:2010, ISO 27001 and ISO 31000. As well as maintaining the software’s existing functionality, the browser-based Q-Pulse 7 comes with powerful dashboards for increased business intelligence and an intuitive user experience.

600V three-phase gate driver with smart shutdown
The STMicroelectronics STDRIVE601 3-phase gate driver for 600V N-channel power MOSFETs and IGBTs provides ruggedness against negative voltage spikes down to -100V and responds to logic inputs in 85ns. Featuring smart-shutdown circuitry for fast-acting protection,
the STDRIVE601 turns off the gate-driver outputs immediately after detecting overload or short-circuit,
for a period determined using an external capacitor
and resistor. Designers can set the required duration, using large C-R values if needed, without affecting the shutdown reaction time. An active-low fault indicator pin is provided. The STDRIVE601 replaces three half-bridge drivers to ease PCB layout and optimize the performance of 3-phase motor drives. All outputs can sink 350mA and source 200mA, with gate-driving voltage range of 9V-20V, for driving N-channel power MOSFETs or IGBTs. Matched delays between the low-side and high-side sections eliminate cycle distortion and allow high-frequency operation, while interlocking and deadtime insertion are featured to prevent cross conduction. Fabricated in ST’s BCD6S offline process, the STDRIVE601 operates from
a logic supply voltage up to 21V and high-side bootstrap voltage up to 600V. Bootstrap diodes are integrated, saving the bill of materials, and under-voltage lockout (UVLO) on each of the low-side and high-side driving sections prevents the power switches operating in low- efficiency or dangerous conditions. An evaluation board, EVALSTDRIVE601, is available to help users explore
the features of the STDRIVE601 and quickly get first prototypes up and running.

Rugged, low voltage capacitors
TDK Corporation introduced DeltaCap
X Black Premium, a new series of
EPCOS MKD capacitors for power factor correction (PFC). Capacitors in the series have rated voltages of between 440VAC and 850VAC. With an internal delta connection, the capacitors are designed for power factor correction and filtering
of harmonics at the low-voltage level.
With capacitance values of 3 x 51 μF to 3
x 165 μF, power correction performances ranging from 20 kvar to 44 kvar (50/60 Hz) per capacitor are achieved. The special black coating improves the dissipation of heat, thereby achieving a very long service life of up to 300,000 hours in accordance with temperature class -40°. Thanks to
the extremely rugged construction, the capacitors of the B32305A* series can withstand a maximum inrush current
of 500 x IR, temperatures of up to
149°F (65°C) and perform up to 62,000 operating cycles per year. The DeltaCap
X Black Premium types are self-healing and equipped with an overpressure disconnector which isolates all three phases from the grid in the event of damage. The impregnation, based on biodegradable soft resin, has an additional positive effect on the heat dissipation.
The capacitors are suitable for use with or without reactors in both conventional and dynamic PFC systems and also for use in tuned resonant circuits in industrial power grids and harmonic filters.
