Industry Standards with spacing distances. For regulatory rules and requirements, see these standards: IPC-2221A, Generic Standard on Printed Board Design, addresses spacing in sections 6.3 and 10.1.4, along with table 6-1. UL 61010A-1, Electrical Equipment For Laboratory Use; Part 1: General Requirements UL 61010B-1, Electrical Equipment For Measurement, Control, and Laboratory Use; Part 1: General Requirements. See Annex C - Measurement of Clearances and Creepage Disstances, Annex D - Parts between which insulation requirements are specified (see 6.4 and 6.5.2) UL 60950, Safety of Information Technology Equipment NFPA 70 - National Electrical Code®. An old, obsolete version for reference is available online . See pages 774-775, table 490-24 UL 840, Insulation Coordination Including Clearances and Creepage Distances for Electrical Equipment. These requirements cover an alternate approach to specifying through air and over surface spacings for electrical equipment through the use of the principles of insulation coordination.
Corona: A phenomenon that has the capability for degrading insulators, and causing systems to fail. In this discussion, formulas are provided to calculate the voltage at which corona occurs, and a mention is made of a useful application for corona.
Circuit makes simple high-voltage inverter: A simple high-voltage MOSFET inverter solves the problem of driving a high-side MOSFET, using a low-voltage transistor. You can drive the circuit with a single CMOS gate. This circuit is probably the simplest high-voltage inverter you can design.
