A Better Balance

ABSTRACT It's an incredibly important moment to focus on work-family scholarship – and to consider research related to ‘just’ work and care in unsettling and challenging times. Against this backdrop, the 2022 WFRN theme was established. The conference gathered members from around the world toward building impactful scholarship for practices and policy. In this Voices piece, we draw upon WFRN presidential panelists' voices. The first plenary, ‘The Meanings of Work-Family Justice’, provided opportunities for panelists to consider different ways to conceptualize and expand this idea as labor markets, workplaces, and many aspects of people's lives are in flux, with new understandings about how to think expansively about creating ‘work-family justice’, The second plenary – ‘Work-Family Justice on the Ground’ – featured panelists from leading non-profits who discuss how they've met challenges and succeeded in implementing and building policies that create a more just world of work and care. They discuss barriers and some ideas for overcoming difficulties. We conclude by considering the evolving meanings and practices of work-family justice. In all, the voices presented here help us focus on creating more ‘just’ worlds of work and care – a distinct and vital – if sometimes precarious – possibility in this moment.

Determining the suitability of a medium-voltage motor which will be installed within a hazardous location as outlined in IEEE 1349, powered by a multilevel, voltage source, adjustable speed drive that is not isolated by a phase-shifting transformer requires two key items to be investigated: thermal heating due to the current harmonics, and the energy contained in uncontrolled sparking from the motor shaft to ground. This paper reviews the process that was used for a possible application of a drive with a motor in a Class I, Division 2 environment, along with modifications that were made to the design and operation of the drive to meet the stated requirements.

This paper presents an implementation of deadbeat-direct torque and flux control (DB-DTFC) for AC induction machine drives that demonstrates nearly ideal properties over a wide range of flux and torque operating conditions, including deep field weakening. A key attribute of this DB-DTFC is that the control law is the same over the entire operating space, including steady-state and transient operation at the voltage limits. By comparison, field oriented control at the voltage limit is inherently compromised and requires adjustment of the current control laws. Similarly, PI control-based DTFC becomes oscillatory under voltage limit conditions. This DB-DTFC implementation requires no change to the control law under voltage limit conditions. This paper presents an implementation of DB-DTFC and experimentally demonstrates its performance over a full range of operating conditions, including operation at the voltage limit.
