Abstract
A power conversion apparatus includes: a power module that converts an input of alternating current power into direct current (DC) power and outputs the DC power; and a gate driver unit that includes a first substrate having mounted thereon a gate driver circuit component that isolates a control signal input from a control apparatus, that converts the isolated control signal into a gate signal for driving the power module, and that outputs the gate signal, a second substrate that includes a wiring conductor fixed to a gate control terminal of the power module, and a connection member that includes a connector that connects the first substrate and the second substrate to each other.

A power conversion apparatus comprising:
- a power module that converts an input of alternating current (AC) power into direct current (DC) power and outputs the DC power, the power module having a gate control terminal;
- and
- a gate driver unit that includes
- a first substrate having mounted thereon a gate driver circuit component that
- isolates a control signal input from a control apparatus,
- converts the isolated control signal into a gate signal for driving the power module, and
- outputs the gate signal,
- a second substrate that includes a wiring conductor fixed to the gate control terminal of the power module, and
- a connection member that includes a connector that connects the first and second substrates to each other, the second substrate receiving the gate signal from the first substrate through the connection member.
A power conversion apparatus comprising:
- a plurality of power modules each of which converts an input of alternating current (AC) power into direct current (DC) power and outputs the DC power;
- and
- a plurality of gate driver units that each includes
- a first substrate having mounted thereon a gate driver circuit component that
- isolates a control signal input from a control apparatus,
- converts the isolated control signal into a gate signal for driving the power module, and
- outputs the gate signal,
- a second substrate that includes a wiring conductor fixed to the gate control terminal of the power module, and
- a connection member that includes a connector that connects the first and second substrates to each other, the second substrate receiving the gate signal from the first substrate through the connection member.
